LASER SYSTEM COMPRISING PASSIVELY Q-SWITCHED MICROCHIP LASER AND GAIN-SWITCHED MICROCHIP LASER

摘要

A passively Q-switched laser (110) is pumped by a first optical input signal (101) to produce a train of optical pulses (102) at a first wavelength. These pulses are then fed into a gain-switched (120) laser. The absorption of energy at the first wavelength induces gain in the cavity (160) of the gain-switched laser (120) at a second wavelength, resulting in the spontaneous generation of an optical output pulse (103) at a preferred eye-safe wavelength.
