ABSTRACT:
A harmonic system for use with metals and alloys such as titanium, steel, copper, gold, aluminum, etc. is disclosed. The harmonic laser system includes 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 for optically pumping the active medium to produce a first optical beam at a fundamental wavelength and a non-linear optical crystal positioned in the oscillator cavity to generate a second optical beam at a harmonic wavelength of the first optical beam, wherein the harmonic separator mirror outputs the second optical beam and reflects the first optical beam.
