3.3.5 HeNe Lasers - The major reasons for including HeNe lasers as candidates are that they are readily available, have proven very reliable, and can be operated at either of two wavelengths (632.8 nm and 1150 nm) where fiber losses are not too severe. ... applications might benefit from the ability to select a specific wavelength or to toggle between different wavelengths. ... The electron beam is modulated to provide pulsed outputs up to 50 nsec in duration, at up to a 3% duty cycle.
