Hello everyone, I recently bought a 574nm dpss laser from Lasence. it arrived today, when I turned it on, I was met with a golden yellow, not as golden as a 589 but more than the opt 575. When I tested it out on my Spectrometer, It showed a wavelength between 577nm and 580nm. I decided to underpower the laser to see what the pump diode is, I expected it to be infrared like all the other dpss lasers I owned but to my surprise, I got a greenish blue light from the laser, it was to weak to test with my spectrometer. if someone knows, can someone tell me what wavelength this green light is? also The module looks slightly different than my optlaser 575. If you need to see any pictures of the spectrometer graph or the module, I can send post It.
