ABSTRACT:
A multiple crystal, single pumping cavity laser system comprises an optical pumping chamber, several laser crystal rods disposed in the chamber 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. All of the laser rods are disposed and pumped in a single pumping chamber. The housing containing the pumping chamber is thermally and mechanically isolated from the rail holding the other system components to prevent shock from being transmitted to the other components.
