Abstract:

This application discloses a cascaded laser system providing optimum stable shot-to-shot reproducible modelocking of high power lasers, particularly gain or Q switched lasers, such as high pressure CO2 TEA lasers and Ndglass lasers. The system combines both active and passive modelocking techniques so that the stable generation of ultra short, high power pulses of fixed timing is provided over a wide range of system parameters. In the system, active modelocked pulses generated by relatively low power laser modulates the loss of a saturable absorber associated with a relatively high power laser in such a manner that during buildup of modelocking the high power laser exhibits the characteristics of an actively modelocked laser but thereafter exhibits the characteristics of a passively modelocked laser.
