Hello all, Just got a 2W 445nM diode here: 2W Copper 445nm M140 Blue Laser Module w x Drive 405 G 2 Glass Lens | eBay it works a treat, but gets hot quickly. The seller says "90 seconds on 30 seconds off with proper heatsinking". If I had a big enough heatsink (maybe even a water cooled one) -...

Hi All, Just bought a IR laser diode here: One Extra High Burning Power 1000 1500mw Infrared to 5 9mm Laser Diode Gift | eBay and they say " Typical operation current is 1.2A Typical operation voltage is 2.0V Maximum operation current depends of the diode, the interval value is around 1.2A -...

Hi folks, I purchased a "808nM, 1000mW, TO-5 laser diode". eBay - The UK's Online Marketplace There is no datasheet attached. I was wondering if you could recommend a module (heatsink + optics) like what aixiz is doing?? many thanks Thomas

Hi folks, Bought a "TO-5 808nM 1000mW" laser diode on eBay (no datasheet available) - I was wondering if you could recommend some optics/heatsink combination for this, in TO-5 diameter - like the Aixiz focusing assembly? many thanks Thomas

Hi there, What is the best wavelenght for cutting/engraving? I am planning on getting a blu-ray 100mW and/or a IR 808nM 300mW laser for very light work on a DIY XY table - what would you recommend?? I am sure it is not all down to wattage... many thanks Thomas

Hello Folks, I would like some advice on laser safety. I am trying to build an XY table, with a laser to do some engraving on substrate. The lasers I plan to experiment on will probably be Blue Ray (404 nM, 100 mW) and IR (808 nM, 300 mW). I intend to do all the tuning etc with a (relatively)...
