Hola,
I have the laser seen below and have reviewed the associated guidelines and classifications. Since the supplier has not yet supplied the datasheet, I wanted to confirm the module is safe to use for my nefarious purposes.
At the rated voltage, power is around 125mW. This agrees with Optical Power vs Forward Current graphs suggesting a 5mW laser with a class 3a rating. Charts indicate this power level is unlikely to start a fire which is the main concern.
The project includes a laser beam that is always moving. The beam may be passed through filters, reflected / scattered by minerals or machined metals and focused on a wall directly.
Aside from general use, I also would like to explore the possibility of accidentally focusing the beam instead of spreading it out (please forgive the terminology) by means of a concave surface or the like.
Specifications
Class IIIa laser diode module
650nm (red) dot output
6mm diameter (0.235″) x 13.9mm (0.55″) overall length
Dot spread at 15M distance measures 10-15mm diameter
5VDC maximum input
-36 ~ 65°C operating temperature range
Prewired with 75mm (3″) wire
1.4g
