Harmonic pulse laser apparatus and method for generating harmonic pulse laser beams
Abstract
A KTP crystal (10) is irradiated by a long-pulse fundamental wave pulse laser beam having a pulse width of 100 µs or longer typically output from a solid-state laser such as YAG pulse laser. In the KTP crystal (10), wavelength conversion is performed to generate a second harmonic pulse laser beam with a two times higher frequency, which long-pulse second harmonic pulse laser beam is in turn output for laser processing such as welding etc.
