US Patent 7088744 Laser for use in non-linear optics

The combination of coupling modes and a Q-switch allows amplitude modulated laser pulses to be produced which contain a high output capability and high repetitive rate. The envelope of the pulse of the coupling modes in the shape of a Q-switch-pulse varies in intensity. Preferably, said combination is achieved by using a saturable semiconductor absorber mirror (SESAM), whereby the parameters thereof must be specially adjusted to the other elements used, so that the requirement for high repetitive Q-switch-pulse rates can be met.
