Multiple crystal pumping cavity laser with thermal and mechanical isolation
First Claim
1. A laser system comprising:
- an optical pumping chamber;
a plurality of laser crystals enclosed in said pumping chamber each of which requires a different optimum level of pumping energy for generating a desired mode therein;
pumping means for optically supplying energy to said pumping chamber at a level which is optimum for a first enclosed laser crystal requiring the highest level of pumping energy; and
attenuating means disposed within said pumping chamber for selectively limiting the pumping energy supplied to each, except the first, of said laser crystals to a level that is optimum for generating a desired mode therein.

Abstract
A multiple crystal, single pumping cavity laser system comprises an optical pumping cavity, several laser crystal rods disposed in the cavity and having differently sized diameters and with their axes parallel, an optical coupling device for coupling the rods in a chain of increasing diametrical size, an optical pumping source for providing an optimum pumping level for the largest rod, and attenuators for all but the largest sized rod for attenuating the energy absorbed by the smaller rods. Since all of the laser rods are disposed and pumped in a single pumping capacity, only a single pumping source is required. The housing containing the pumping cavity is thermally and mechanically isolated from the rail holding the other system components to prevent shock from being transmitted to the other components.
