And here the spectrum: 2.5 nm FWHM centered at 588.5 nm. I don't remember if this is the wavelength in air or was already converted to vacuum wavelength, but the difference should be 0.2 nm approximately.

I disassembled the same laser in 2015, at the beginning of my PhD... and yes, out of infinite curiosity to inderstand how 589 nm light was generated in such small thing. Naively took the SHG crystal out/in from the cavity and the device stopped lasing, unexpectedly at the time. It took me...
