METHOD AND LASER DEVICE FOR GENERATING PULSED HIGH POWER LASER LIGHT

摘要

A method of generating pulsed laser light (1) comprises the steps of providing laser light pulses (2, 3) having a predetermined pulse repetition rate (frep) with a laser source device (10), coupling the laser light pulses into an enhancement cavity (21) with a plurality of cavity mirrors (21.1, 21.2,...) and a predetermined cavity length (L), and coherent addition of the laser light pulses (2) in the enhancement cavity so that at least one cavity pulse (1.1, 1.2,...) is formed, wherein the at least one cavity pulse (1.1, 1.2,...) circulating in the enhancement cavity (21) irradiates all of the cavity mirrors (21.1, 21.2,...) with an angle (a) of incidence of more than 45°. Furthermore, a laser device (100) being configured for conducting the method is described.
