200mW green DPSS module
Green laser module but has only around 100 hours of use
It do >250mW with very good conversion efficiency (950mA on the 1W pump diode) and is very stable with real TEM00 mode.
Temperature is well controled : a fan in the power supply; a TEC, fan and heatsink on the laser head, so you don't need to attach an extra heatsink, it runs cool for hours. It's a Fengyuan unit (which was a special model built for Crystal Research which I think is a sign of quality, you can see here www.cresearch.net Of course it has an IR filter...
I sell it because it's way too powerful to mix with my other lasers (red and blue) and I need analog blanking...
Price is 420$ shipping worldwide included(with tracking and insurance). And don't hesitate to ask if you have questions. Pictures will follow later
