Back to Commercial Solid State Lasers Sub Table of. Coherent Compass M Green DPSS Lasers. Note Information on adjustment and repair of these lasers has been moved. SS Laser Testing, Adjustment. Originally, there were three lasers in this family The C2. M, C3. 15. M, and. C4. 15. M. They are all very high quality 1. W green. DPSS laser manufactured by Coherent, Inc. It is one of their Compass series. Information and datasheets may be found. Product, Lasers, Diode Pumped Solid State Lasers, and. CW DPSS Lasers links at their Web site. Now as of 2. 01. SLM C1. M discussed. The C5. M uses. C3. 15. M, but it is not known whether this is always. There was also an older OEM model called the C3. M FP, a fiber coupled. C3. 15. M controller. The C1. 15. M and C3. M FP described after the C2. Sol Trigger English Patch here. M, C3. 15. M, and C4. M. These lasers were originally developed by a company named Adlas Advanced. Design Lasers in Germany. Adlas was bought by Coherent but only the newer. Coherent part number. They all appear to still be. Germany. Older C3. Ms have a DPY3. 15. M model number but. PCB which. are mostly artwork related, they appear functionally identical. There were a number of earlier Adlas models with a similar basic design. See the sections starting. Adlas 3. 00 Green DPSS Laser. The third generation Adlas laser designs which includes the C2. M, C3. 15. M, and. C4. 15. M, were a major upgrade and so Coherent than just bought Adlas to. The Ads for the Adlas. DPY 3. 15. M only ran for a couple months and then they came out as Coherent. According to information that used to be on the Coherent Web site, the C2. M. and C3. 15. M are supposed to be single frequency single longitudinal mode. The only reference still present there. Comparison Chart for Continuous Wave CW Solid.

One current specification in. RMS from 1. 0 Hz to 1 GHz for the C3. M and C4. 15. M and 0. RMS for the. C2. 15. M. This would most likely be orders of magnitude higher. And I did do some tests of. C3. 15. M laser head and indications are that it is indeed single. See the section. Testing the C3. M. Laser Head for Single Frequency Operation, which also includes some. However, note that the Coherent chart. C4. 15. M is broadband meaning not single frequency, yet it still. Ive only known of a few C3. M lasers that operated non single frequency. Coherent controller. One would just mode hop. Hz between two very clean modes at certain power. Another had ghost modes at any power setting with associated spiking. And a third would do this but mostly at higher power. However, I was able to get a randomly selected C3. M laser. head to produce a low level but stable second mode when driven using. Nd YAG gain curve. But it would run reliably single frequency on the. Coherent controller. Also, some units will briefly go to non SLM during. KTP andor RES temperature is changing. Ive also seen one C3. M that produced a very low level less than 2. None of this is particularly conclusive with. C3. 15. M lasers because Ive never seen one. All those Ive tested have been either removed from service due to. Adlas and Coherent have both waffled on guaranteeing SLM operation. They will only say that most of the units are SLM most of the time. I assume that when stabilized near the middle of the gain curve, they. SLM. But if the controller gets carried away trying. SLM operation. And some units are more prone. Most of the information below is for the C3. M since these laser heads have. Coherent Analog. Controller LD and TEC driver unit with analog user interface, and. Digital Controller which plugs into the Analog. Controller and adds a computer interface but doesnt subtitute for. Analog Controller. The C3. 15. M is available in. W though the most common one on the. W rated version, the C3. M 1. 00. The output. The maximum user adjustable power may be set by. There is no modulation capability. There is also a Coherent Compass 4. M which is higher power versions up to. W but bears much similarity to the C3. M. However, it was. It uses a slightly different and. The. head PCB which includes the personality settings for the laser is more. C3. 15. M. see below but its possible that the actual internal wiring of the head. At least there are the same number of pins going inside. See the sections starting with C4. M. Laser Head for more info. Most references to the C4. M have now. disappeared from the Coherent Web site as it is no longer being. The other laser in the original Compass M family is the C2. M, a lower power. W. It is much more similar to the C3. M than. the C4. 15. M but the controller is definitely not the same and has a lower. The overall system is probably. C3. 15. M. I have tested a C2. M 7. 5 laser head on both. C2. 15. M and C3. M controllers and it works fine. But whether the stability. C3. 15. M controller is not known, though. Id expect them to be similar. Due to the method of construction, all three of these lasers should retain. Everything internally is fastened by. A fall onto a concrete floor. In 2. 00. 5, Coherent has added a C1. M laser to its product line. This is. a low power 5 or 1. W laser which uses a very different design. It. has obviously been cost reduced the blurb even says so, as the controller. PCB that fits over the laser. Given the configuration of the laser. The C1. 15. M has a more conventional cavity design than the other. Compass M lasers and it is not single frequency. And, if you happen across a truckload of junked lithosetters, rumor has it that. C3. 15. M lasers is the Agfa Galileo, which is an. Newer ones are now using violet laser. As of 2. 00. 6, there is a Coherent C5. C3. 15. M design but with different. SHG crystal or just phase matching angle. Nd YAG. has a lasing line at 1,1. Bypass BIOS Boot or OS Login to most Any Computer. With Console Access 6 Steps. Bybassing BIOS Solutions 1. BIOS passwords secure different levels of system access. Lowest level is access control for power management functions, next for BIOS access BIOS password and highest level is for PC access Administrator password. BIOS password is stored in a non erasable part of the CMOS BIOS memory. On desktop PCs this CMOS is buffered by an onboard battery. Depending on your mainboard layout youll see a seperate battery or wont see it as it will be integrated in a multifunction chip housing battery, real time clock RTC and other components usually a small black brick on the mainboard. Keeping that in mind different ways of removing the password are possible. Remove password with some kind of software. This works only if you have access to your PC and can run software meaning no Administrator password is set. CMOSpwd www. cgsecurity. Remove password by manually invalidating CMOS content. When CMOS RAM loses power, a bit is set to indicate this, which should cause the BIOS to detect that the CMOS RAM is invalid and will normally result in the loading of default values. The same results can be obtained by using a simple DEBUG script to invalidate CMOS RAM. This may be much more convenient than shorting pins on a chip in cases where it is possible to boot to a DOS prompt to run DEBUG. Here is a DEBUG script to invalidate CMOS RAM. This should work on all AT ATX motherboards some systems do not have CMOS RAMBoot from floppy with DOS or USb thumb drive. A DEBUG o 7. E o 7.

Remove password using Clear CMOS jumper on your mainboard. Please refer to your manual to locate this jumper. Clearing CMOS will erase all passwords set but all your user defined settings like harddisk type, RAM timings etc, too. Youll have to set these values again after clearing CMOS. Remove password by clearing CMOS due to disconnected power. CMOS content is buffered by an onboard battery. If you disconnect this power supply your CMOS clears automatically as the content cant be refreshed due to the missing power. This works easily if you see the onboard battery. Remove the battery for at least 5 minutes an insert it again in its socket. Remove password by clearing CMOS within RTC chip. Depending on the RTC chip used on your mainboard you can reset CMOS content by connecting two pins on the RTC chip. A paperclip bent into a U shape is a good tool for this. For all the following activities your PC has to be powered off. Chips Technologies P8. C2. 06. This is usually a square PLCC chip, sometimes soldered onto the motherboard, sometimes in a socket. CMOS RAM on this chip is cleared by shorting together pins 1. GND and 3. 2 5. V or pins 7. GND and 7. V for a few seconds. Pins 1. 2 and 3. 2 are the first and last pins on the bottom edge of the chip, pins 7. OPTi F8. 2C2. 06. This is a small rectangular PLCC chip usually soldered onto the board. CMOS RAM is cleared on this chip by shorting together pins 3 and 2. Pin 3 is third pin from left side and pin 2. Dallas DS1. 28. 7 and benchmarq bp. MTCMOS RAM cant be cleared. Instead you can replace RTC chip with a new one. You can even use an updated version DS1. A or bq. 32. 87. AMT which support CMOS clearing. Dallas DS1. 28. 7A and benchmarq bq. AMTThis battery should last up to 1. Any motherboard using these chips should not have an additional battery. CMOS RAM can be cleared on the DS1. A and bq. 32. 87. AMT by shorting pins 1.
