  • INFRARED BE CAREFUL

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:

    Cheap. Powerful.

    Cons:

    I measured 350mW of infrared light(!) coming out of this thing. The infrared light is not filtered. This is primarily an infrared laser with 50mW of green light. Could cause serious damage to your eyes even if you are wearing safety goggles for green.

    OtherThoughts:

    A single set of safety goggles WILL NOT PROTECT YOU, unless it blocks the wavelength of the pump laser (808nm and 1064nm).

    Bottomline:

    If you value your eyes, get some goggles that cover 532, 808 and 1064nm... or use a piece of heat absorbing glass in front of the laser as a filter.
