Abstract
A passively Q-switched laser is pumped by a first optical input signal to produce a train of optical pulses at a first wavelength. These pulses are then fed into a gain-switched laser. The absorption of energy at the first wavelength induces gain in the cavity of the gain-switched laser at a second wavelength, resulting in the spontaneous generation of an optical output pulse at a preferred eye-safe wavelength.
