Don't use a green laser in the cold!
🕑 Added 2020-08-30 17:18:55 +0000 UTCTime to bring some public attention to the risk of using green DPSS lasers in the cold.
I know green lasers are used to point out stars on frost-clear nights, and Christmas decoration lasers are used outside at winter too.
But are people aware of the invisible hazard from an apparently non-working laser? In this video I try to show how bad it can be.
And as a sidetrack, I test the wavelength of my IR remotes :)

For the spectrum, I am using a Lasertack LR2 in the 200-1200 nm version. Very similar to the ASEQ Instruments LR1 - just rebranded for the European market. The laser power meter is a Tracer 20W Laser Power Meter from Sanwu Lasers. I am currently testing a much cheaper and simpler laser power meter. Stay tuned for next video here on Patreon and my YouTube channel ;)
What brand/model of the test equipment you are using to measure spectrum & power?
