Title: LASER DEVICE
Abstract:
The invention relates to a laser device (1) that is provided with a pump element (2) that contains a pumped laser crystal (3) and with a device such as a saturable absorber (15) for passive mode coupling. The device is provided with two separate, alternatively switched resonator arms (11, 12). One (11) of the resonator arms that is active in the pulse shaping phase (21) contains the saturable absorber (15). The other resonator arm (12) that is active in the reinforcement phase (22) is free of loss-related components.
