I have two good guesses on the wavelength of the laser device:  0.9 microns
being the most common cheap GaAs laser diodes or 1.54 micron being in the
"eye-safe" zone for which diode laser also exist.  I am checking the eyesafety
standards ANSI publication Z 136.1 - 1980 to see if that will give me a clue
to the frequency and/or output power
