FEEDBACK AND AMPLIFICATION
drive the "lasing" process when many different wavelengths, or modes,
of light oscillate in the cavity in precise synchrony , they add up to
produce an intense pulse . A periodic sequence of pulses emerges through the partially transmitting mirror.
The synchronization is obtained with the passive absorber mirror SESAM.
Output pulse width 1.6 ps Energy 5pJ and a peak power of 3.1 W. The repetition rate 20 GHz www.swissrocketman.com
