    Default 660 nm DPSS lasers: do they exist?

    There is a question that I have been unable to get a definitive answer to, and I thought that you guys might be able to help.

    Some time ago, I noticed that a company ( was selling a 660 nm laser that is supposed to output 300+ mW. The beam specs are very good (1.5 mrad at 1.5 mm), so I suspected that it was a DPSS laser that uses a frequency-doubled 1,320 nm beam. (Diode lasers usually have far worse specs.)

    However, users from other forums (CPF, LPF, and Spectra Forum) said that it was a diode laser and told me that 660 nm DPSS lasers currently don't exist. The specs seem too good for a diode laser, but then again, has been reported to be a "shady" company.

    I'm inclined to go with what the other users are saying, but Viasho, a well-reputed manufacturer, claims to sell 660 nm DPSS lasers.

    So do 660 nm DPSS lasers exist after all?

    Viasho do have 660nm DPSS red laser,but the power is around 15 watt.

    But it's not a CW Laser,it's QCW.
