    Harvesting / Teardown of the Pico1 Projector - 450nm, 640nm, + non-DPSS Green

    Hi, Here's a bit better view of the green laser.

    Harvesting / Teardown of the Pico1 Projector - 450nm, 640nm, + non-DPSS Green

    Here's my best guess of the parts and the beam path. Any ideas what's the part after the gain crystal?

    Didn't fire it up yet... I think the laser has an optically pumped Nd:YVO or semiconductor gain medium. The nonlinear crystal is periodically poled (visible under microscope) and sits on top of a thin film heating element. The cavity end mirror seems to have a concave inner surface.

    Harvesting / Teardown of the Pico1 Projector - 450nm, 640nm, + non-DPSS Green

    Hi, Here's a photo of the cavity of the green laser. It seems to be built on a silicon substrate.
