Abstract
A compact diode pumped laser including a nonuniform, single-or double-sided diode pumped laser head and a polarization output coupled (POC) resonator. The POC resonator employs reflections from two opposing uncrossed roof prism mirrors to produce a uniform near field and far field beam with diffraction or near diffraction limited quality. The single laser head particularly includes a laser rod, a sapphire envelope located about the rod, an area of antireflection coating located on the sapphire envelope between the rod and the diode array, and a high reflectivity nickel-plated indium layer located on the sapphire envelope on the surface thereof outside of the area of antireflection coating.
Claims15
A laser head comprising:
- a lasing medium comprising a laser rod;
- a single pumping diode array positioned adjacent said lasing medium;
- a sapphire envelope located about said rod;
- an area of antireflection coating located between said rod and said diode array;
- and
- high reflectivity coating means located on said rod outside of said area.
A laser head comprising:
- a lasing medium embodied in a rod geometry;
- a single pumping diode array positioned adjacent said lasing rod;
- a sapphire envelope located about and directly abutting said lasing rod;
- an area of antireflection coating located between said lasing rod and said diode array;
- and
- high reflectivity coating means locate on said sapphire envelope outside of said area;
- wherein said high reflectivity coating means further provides a cushion between said sapphire envelope and a metal housing base.
A laser head comprising:
- a lasing rod including a lasing medium;
- said lasing rod having an axis extending through a center of said lasing rod;
- and
- first and second pumping diode arrays positioned adjacent said rod medium;
- wherein said first and second pumping diode arrays are positioned on a same side of said axis of said lasing rod.
