Default Mitsubishi 638nm 300mW laser diode melting CD case

This is my newest laserdiode. It is the Mitsubishi 638nm 300mW laser diode.
With a 405-G-2 lens and 965mA current it burn thought the case in few seconds.

The 445nm hotlight is set at 1350mA.

What did you run the 638nm diode at?

The 638nm diode was run at 965mA. According to the review it was close to the maximum output.

not all glasses will protect ypur eyes on these--look here to see a possible GB for ones that do. PM me here if you want a pair- substantually cheaper than a seeing eye dog.

Good quality EYEWARE for the new 635 diodes possible GB

That is quite a bit of current consumption for a red diode!
However upon further reading it's a multimode diode. This makes a huge difference!
Peak output is just shy of 500mW at 1A !

I already got a glass for 445nm color but I am looking for a 635-650nm glass. This 638nm is bright, a glass is much needed.

500mW at 1A is done with a normal Aixiz glass. According to DTR a G1/G2 glass add another 30% increase in power. The power is close to 650mW of red power.
