Abstract:
1. A harmonic laser system, comprising: an oscillator cavity having a first end mirror and a harmonic separator mirror, an active medium positioned in the oscillator cavity; an electro-optic pump device comprising a pulsed power source for optically pumping the active medium to produce a first optical beam at a fundamental wavelength and having a peak power of a non-linear optical crystal positioned in the oscillator cavity for generating a second optical beam, which is suitable for laser welding, at a harmonic wavelength of said first optical beam in response to converging the first optical beam onto the non-linear optical crystal, the harmonic wavelength being a green wavelength; and a focusing lens for converging the first optical beam to the non-linear optical crystal, wherein said harmonic separator mirror outputs said second optical beam and reflects said first optical beam.
