Title: REGENERATIVE AMPLIFIER AND METHOD OF COUPLING A LASER PULSE IN AND OUT
Abstract:
Regenerative amplifier (1) and method of coupling a laser pulse (3) in and out of the regenerative amplifier (1) comprising: - a laser pulse generator (2), - a laser cavity (4) defined by mirrors (5; 5a, 5b, 5c, 5d, 5e, 5f, 5g) for passing a laser pulse (3) along a laser pulse path (6) extending between the mirrors (5; 5a, 5b, 5c, 5d, 5e, 5f), - a first gain medium (7) arranged in the laser cavity (4), - a first polarizer (9) for coupling in a laser pulse (3) having a first polarization state, - a switch element (11) for switching the laser pulse (3) from the first polarization state into a second polarization state and vice versa, - a second polarizer (10) for coupling out a laser pulse (3) having the first polarization state, wherein - the laser pulse path (6) in the laser cavity (4) comprises an input path section (6a) for coupling in the laser pulse (3) and an output path section (6b) for coupling out the laser pulse (3), wherein - the input path section (6a) is arranged at an angle (a) to the output path section (6b) such that the input path section (6a) intersects the output path section (6b) at an intersection (12), wherein - the switch element (1) is arranged such that the input path section (6a) and the output path section (6b) extend through the switch element (11).
