I meant, that I hope the laser to emit < 489nm of light, since I am more fan of blue lasers.
Then you'll very likely be quite happy with your spiffy new laser; the first unit spectroed at 488.7nm and the replacement laser came in at 489.4nm. :)

This thread is GOLD for those wanting a cyan beam...for not too much money.
I was enjoying mine earlier! My favorite color by far...and yes even at 66mw it
etched my initials on my dark wood desktop...very faintly!

Thanks again LED and happy 4th!

I will definitely whip the class 4 lasers out for beamage into the sky...in the past
the neighbors cheered!

Photograph of the laser's beam in fog; I used the camera in one of my cellular telephone handsets to capture this.

I have a Sharp diode driven at 275 mA that measures exactly at 488nm with an acrylic lens at 135 mW output power. The part number is: GH04850B2G. I did a review of that with photographs of the build with bean shots.
