Advanced Phased Array Chemical High Energy (APACHE) Laser Program Volume 1

Abstract

Volume I of the final report for the Advanced Phased Array Chemical High Energy (APACHE) laser program presents phase conjugate laser technology which verifies and demonstrates the key technologies associated with phase conjugation of high power continuous wave chemical lasers using stimulated Brillouin scattering (SBS). These demonstrations include: SBS under long pulse conditions simulating CW operation that demonstrates the feasibility of using SBS for a high power, CW laser; near diffraction limited performance for beam combination at the HF wavelength using SBS in high pressure xenon; flowing-gas SBS cell experiments demonstrating fluid mechanics capability for using a flowing SBS medium for CW SBS applications; SBS conjugation experiments using a 19-element segmented mirror showing the ability of SBS to correct piston and tilt misalignment errors in a multielement segmented optic; and experiments to determine how feedback to the master oscillator from the SBS cell affects system performance.
