Laser Module - Green

Replacement:COM-09906. We found a better, cheaper supplier so this module has been retired.

A very powerful 5mW green laser. Fun, but don't point in anyone's eyes. These units have the power wired in such a way that the unit turns on when power is applied. The wires can be re-soldered to use the momentary switch as well. The trim-pot adjusts the output power. We couldn't quite get it up to the max 300mA, but even at 150mA this green dot is very bright.

  • 532nm Green Laser
  • 5mW output power (FDA Class IIIa)
  • 2.5V to 4.5V input voltage
  • Max current: 300mA
  • 56 x 11mm

    I went to the Wen Tai web site and can't seem to find the PCB layout/schematic. Has anyone figured out the pads to route the power to so that the on board switch is enabled? Also curious what the jumper pads on the back might be for.

    THIS LASER CAN CUT PAPER OR SOME MATERIAL?

      This is a class IIIa, up to 5 mW output power.
      A class IIIb with output power from 6mW to 500mW would be able to cause light skin burns[1].
      I'd say if you want to get paper or some other material cut you would need some very powerful laser beams.

    Does this one have an IR filter?

      This device is at the 532nm wavelength, no need for IR (infrared) filtering which is down beyond the 700nm wavelength.

        green laserlight is made by sending infrared light of 1064nm* through a prism. so i'll ask again, is there a IR filter
        *could anyone confirm this? i don't know the exact wavelength.

        • danvm / about 14 years ago / 1

          you are correct oddish2211, the diode in a green laser emits at 808nm, which is in turn converted to 1064nm and finally doubled to 532nm.
          i would also like to know whether this laser has an ir filter in it, without one it can and will emit >50mw of both 808 and 1064nm radiation wich is both invisible and dangerous if proper eye protection is not worn.
          most low cost modules made in china lack the filters and the datasheet is not helpful at all.
          (btw, contrary to the description, 5 mw is not really all that powerful for those who dont know.)
