I need to make (because buying is out of the question, price is way too high) an insanely powerful green dpss module for lightshows, and I've found something very interesting on ebay - DIRECT 3w 1064nm c-mount diode. Here are my questions: Those diodes are real or is it just scam? With 1064 nm...

Hi I am currently in progress of making a BIG laser show projector, and there is a problem with red module - two 'oclaros' combined with PBS wont be enough for the rest of lasers (green module outputs over 600 mW, blue is a total killer too) , but the big mitsubishi 9mm red diode is too damn...

No idea about their name, one is from polish disco laser scanner circa 100mW output power rated (well known disco equipment producer so they wont give false data), second one is fantasylasers 500mW green as far as I remember (this one has TEC and temperature sensing), both are C-mount. I could...

Hello I have some lasers along my DJ equipment, and currently I am in progress of making quite big RGB laser. I've bought some dpss modules (green) that had broken diodes but good optics and larger crystals (4x bigger than in cheap laser pointers, integrated in long brass ring with temperature...

How much? After currency change approx. $50. What are probable power ratings for this size of he-ne tube?

Hi Yesterday I've won an auction, it was really long and heavy disco laser scanner (seller said it weights over 30 kilos), something I haven't seen before so I decided to buy it. I dont have it yet but seller sent me a photo of inside after I've asked him - there is a REALLY long module looking...

Hello, I just made a laser out of lg dvd burner. Diode is standard mitsubishi LOC, but there is a problem - when I powered it up in sled (this concentrates beam to very fine spot at close distance), I couldnt even light a match (achieved peak output on 390mA 2.8V on my PSU). At this power, it...

I can assure you it was STILL working properly. Up to the moment when I mechanicaly torn the + wire (brass tape). I dont know if it's fixable. During those tests (at rather high voltage) the whole module was cooled by huge radiator, fan, and a pentium III heatsink connected to it just in case

Fixed voltage/amperage lab power supply. This doesn't need a driver. Nothing bad happened to laser by that test

UPDATE: After receiving a lab power supply (3.5A max 15v) I've driven the ir diode at 5v 2.5A after some warming up after placing it in this empty laser stage lightning 250mW scaled DPSS host (with Nd:YVO crystal). The crystal has really good cooling (full contact with aluminum & brass), so I...

UPDATE: Pump diode glowing at low current (driver from 200mw diode). Doesnt even overload my phone camera nor heats anything. Here is the photo - does it show anything? The laser glows in line (without any optic except built in FAC ) , this means for sure it's...

Cant do anything until I buy new mm, one I have is broken. Transistors are probably mosfet because if they were bipolar, after shorting them diode wouldnt even react. Guess just gonna buy lab dc supply to be sure

View image: 20150222 224813 Photo of driver/psu unit. J1 was the problematic transistor (supplying vdc to diode) j2 supplying to fan. Fan works fine after shorting its psu transistor, diode doesnt

Gonna buy a lab supply and check it. I know basic electronics and more, I just have no equipment UPDATE: Those 'jumpers' were base and emiter legs of main power transistors. That means I probably destroyed the power supply (it was merged with a driver). Does short circuiting transistor legs...

Dot looks okay. I decided to disassemble everything and I left only pump diode. I wasnt looking directly (all time through camera). Pump diode INSTANTLY burnt a match but seems like its power is completely random - getting full powee spikes when I touch housing with a screwdriver (sometimes). I...

Hello. A few weeks ago I've bought a 532 nm 1000mw dpss laser with a defect - crystal was misaligned due to kinetic shock this device received and its output power was down to like 100mw. It came with a funny power supply. This power supply had some jumpers and I thought that connecting them...
