Q-switched pumped solid-state laser

The laser has a pulsed pumped light source (30) formed by pumping diodes (3). A solid laser crystal is enclosed into a resonator (9), and a quality switch increases power density. A focusing device (7) focuses a Peltier cooling section (12) to a cooling mechanism (11) for cooling the resonator. The mechanism has cooling systems, where the Peltier cooling section is assigned to one of the cooling systems for cooling the diodes.
