Default No longer FS: 4 WATT OUTPUT DPSS 532nm GREEN LAB LASER - BRILLIANT BEAM AT NIGHT!

The paint has scratches but it puts out full and steady power measured at over 4 watts out and a divergence of 1.5 mRad or better with a 5mm oval shaped beam output, best I can tell. I don't know if the analog input works or not, never tried that.

Sounds like a fantastic deal. If I wasnt awaiting SS and had my job I would buy it As it is I rumble along on tax refund and soon some birthday cash but not that kind of dough. Hopefully someone will treat themselves to some insanely bright super per density 532nm.

That's a crazy deal I'd be interested, but whenever I've had a lab laser it tends to just collect dust and never get used. GL selling this.

I have a man in the UK who is interested, but the price here was for a long term member in the USA or Canada, I fear sending anything to the other side of the planet and have something happen in shipping to it and be responsible for paying shipment back.

Being in the UK always makes complications for me whatever I buy and especially something that has anything to do with optics and lasers, as most parts I get have to come from the US or China. Being right in the middle doesn't help and Europeans charge so much. Also the custom charges are horrendous here.
How much would insurance be, as I believe that would be the best option.

OK, Thank you. If right, it would be worth it. I've had items delivered before and have been OK, but still a huge risk.

EDIT: I no longer need to sell the laser, took a job overseas which doubles my income. I only listed it due to needing money, that has since changed.
