Multipassage optical configuration for a laser employing a saturable absorber.

摘要

The invention regards the multipassage of laser radiation (19) through the same saturable absorber (15), located within a high power laser optical cavity operating through the same saturable absorber which operates in presence of Q switch or Mode locking. Through multiple passages (Figure 1) within the Saturable Absorber it has been demonstrated that very high energy laser pulses and conversion efficiency can be achieved, previously obtainable only through Q switching electronic systems.
