I bought the DTR BDR-209 405nm Laser Diode with the G2 Lens from DTR store.

I'm trying to find the datasheet for the BDR-209 405nm Laser Diode.

I'm sure it should have one since it is a quality laser diode.

The reason I ask is because I'm trying to find the beam quality M2 values for it.

Thanks.

I don't know if they have an official datasheet because they are pulls from bluray drives but I'm probably wrong

I am surprised the radiation angles aren't a bit tighter for that diode because it collimates into a very thin beam and can focus down to a very tiny spot many feet away using just a standard 6.3 mm laser pointer lens. Must be the wavelength, I have found the shorter the wavelength, the easier it is to focus to a very intense tiny spot.
