- Beamshot 1
Here’s a couple of beamshots from the new laser, running at full power.

1.5W 445nm Lab Laser
Here is a followup from the 1.5W laser module post.
The module has been fitted into a housing, with a 2.2Ah Li-Poly battery pack. Charging is accomplished with an external 12.6v DC power supply.
Above can be seen the pair of switches on the top, the keyswitch must be enabled for the laser to fire.
When armed, the ring around the push button illuminates blue, as a warning that the unit is armed.
Inside the unit. The Li-Poly battery pack is at the bottom, with it’s protection & charging circuitry on the top. The switches are wired in series, with the LED connected to illuminate when the keyswitch is turned to the ON position.
The push button applies power to the laser driver module, which regulates the input power to safely drive the semiconductor laser in the aluminium heatsink housing.
1.5W 445nm Laser Module
This is a fan cooled 445nm laser module, which emits in the blue part of the spectrum.
Fan cooled & with TTL control built in, this is the beginning of a new laser projector.
Here’s a quick beamshot:
