Abstract

In a device to generate laser light, with a laser-active main resonator (2) and a coupled non-linear resonator (6), each of the two resonators (2, 6) being delimited by mirrors (8, 4; 4, 10), and one mirror (4) of the main resonator (2) being identical to a mirror (4) of the coupled non-linear resonator (6), it is provided that the non-linear resonator (6) is designed for a power loss less than 63% of the power which is coupled via the main resonator (2) and the mirror which delimits the coupled non-linear resonator (6), and the laser-active main resonator is designed so that in laser operation it has a threshold pump power which is less than one fifth, preferably less than one tenth, of the pump power which is used and using which this resonator is excited.
