S-KY 150mW 473nm laser module - going soon!

[drlava]

Up for sale is a 150mW 473nm analog modulation laser from S-KY that I reviewed a while ago. When kept cool it runs quite over spec, around 180mW, up to 200mW.
Last chance to buy this beast before it gets returned, as the review is complete!

$1600, offers will be considered.

Damn, that is a nice looking unit. Just a bit late... How was the modulation on this unit?

[drlava]

Modulation is good for shows. It starts at 2V (so your software should have a settable threshold) and at high speed (as in shows) it's pretty linear all the way to the end at 5V.

Nice review.
I like how you explain about temperature effecting the power curve.
I have noticed this with all of my DPSS lasers,
I have RPM controlled cooling fans that go by my base plates temps.
This has helped with keeping the lasers somewhat stable

My projectors have TEC controlled beam tables...no worries there. I have my laser torn down to install a better pump diode collimation optic...I would be interested to have you run the "full monty" on it when I get finished...again. BTW a very intensive review.....well done. I assume no internal cavity pix? Would like to know if they have offset the LBO on the M axis to compensate for thermal lensing. Seems a common practice...

Thanks for the comments, yes I could run tests on yours if you like. I promised not to open the cavity seal to keep the laser as new, so the warranty is still fully intact so no info there, sorry .

One think I found on the one they sent me was that the cavity is not sealed. It has a 1mm or so gap around the edges and the wire input is not sealed.

[drlava]

This one has no gap and the wire entrance is tight.

[Laser Ben]

Blow on it over the gap where the top meets the body of the laser. You will hear what I mean. It was for sure not sealed on mine.

[drlava]

Got back now.. I didn't blow on it but lit a laser across the mating area. I still can't tell if there is a glue seal to the optic cavity or not but a thin piece of electrical tape could be applied around the seam for peace of mind if you like.
