Laser Cartridge Concept Development Study

Abstract

A laser cartridge has been developed which incorporates a Nd:YAG laser rod, passive Q-switch and resonator mirror into an integral bonded assembly. The laser rod is 3 millimeters diameter and 15 or 16 millimeters long. Output energy is over 0.5 millijoule when pumped with 1 joule into a Xenon flash lamp. The key elements of the program were: development of a total process for manufacturing nickel-complex dyed polymethylmethacrylate (PMMA) with accurate control of optical density in a high purity damage resistant material; selection of an optical adhesive with necessary dimensional stability and strength while bonding materials with widely different temperature expansion coefficients; the development of alignment and assembly procedures for consistently obtaining good laser cartridges. The program has demonstrated the feasibility and applicability of the ECOM laser cartridge concept.
