Laser pumping cavity
Patent
·
OSTI ID:5364290
In a laser pumping cavity, a laser rod of high gain material; a light source having an outer surface located in spaced parallel relationship to the laser rod to direct pumping radiation thereto and selectively energizable for emitting pumping radiation to establish a population inversion in the laser rod between first and second energy levels to cause laser light radiation therefrom and including a coolant flow tube for directing symmetrical water flow around the laser rod for cooling it during its operation. The improvement comprises: a hollow single piece solid member of reflective glass ceramic material having an outer surface and an inner surface thereon spaced from the coolant flow tube. The hollow single piece solid member enclosing both the light source and the coolant flow tube to serve as the sole reflector surface for focusing light from the light source to the laser rod. The hollow single piece solid member having the inner surface thereof located in spaced relationship with the outer surface of the light source to closely couple the reflective glass ceramic material to the light source. The hollow single piece solid member of ceramic material receiving light from the light source and reflecting light to the laser rod at a reflectance from the inner surface which is substantially equal to the combined diffusivity reflection of the hollow single piece solid member from the inner surface to the outer surface thereof.
