Decent, especially not bad for a 200mW green laser from an unheard of chinese company. And you always have to factor in human error. Nice work!

Interesting laser.. i'm looking forward to any power measurements done on it.

If its close to the stated 200 mW and can keep that output power up for some time, it does seem like good bang for the buck.

so far, the longest ive left it going was about 3 min, and, the entire time it was a clean TEM00, as i had it unfocused, after 3 min it was starting for feel a bit warm, so, i let it rest

Doesnt sound bad then - was it still just as bright after 3 minutes of runtime?

is this the laser you wanted to trade me?

If so PM me so we can wrap it up otherwise let me know if you do not want to trade as I am going to get one of daquins 8x br lasers if he still has any available after I hear from you.

thanks
