If anyone sees a 1154 nm laser diode or bar array for sale at surplus prices, please let me know. These are used in OPSL lasers to produce 577 nm yellow. I have recently found a dead 577 nm laser head which needs a good diode, if I find anything I can probably make it work.
Sure. Will do
It’s the same head used in the good 577 nm lasers I bought, this one has very low output, under 70 mw due to a weak diode, I’m told. Should do 2 watts output. I will get it in the mail soon.
I have recently learned the 577 nm head uses a ~800 something nm pump diode, likely 808 nm as a common pump diode, not 1154 nm. That wavelength is produced with the BRF crystal tuning and with a NLO doubled to 577.
We need to investigate InGaN pumped 577’s too
