Abstract:
A laser comprising;a) a fist reflective surface and a second reflective surface forming an optical resonator cavity therebetween; b) said optical resonator cavity having an optical axis between said first and second reflective surfaces; c) a laser medium having a front and back end located within said optical resonator cavity along said optical axis for generating a fundamental frequency laser beam propagating from said front and back end of said laser medium; d) said first reflective surface highly reflective for fundamental beam; said second reflective surface at least partially reflective for fundamental beam; e) a first diode end pumping apparatus for pumping the front end of said laser medium; f) said optical resonator cavity configured to impart a laser beam diameter in the laser medium from about 0.8 mm to 2.0 mm in diameter for said fundamental beam; and g) said laser medium having a diameter from about 1.6 to 5 times said fudamental laser beam diameter.
