Laser Cartridge Concept Development Study

reportActive / Technical Report | Accession Number: ADA024442 | Open PDF

Abstract:

A laser cartridge has been developed which incorporates a NdYAG 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.
