Multiple internal reflection face-pumped laser

摘要: A miniaturized face-pumped, face cooled laser device is described wherein wave front distortion minimized by the passage of a coherent beam electromagnetic radiation through an elongated, rectangularly cross-sectioned body in offaxial direction to effect multiple total internal reflections from fluid cooled, parallelly extending faces body. Because each ray passes substantially identical thermal environments during reflective transmission body, net reduced making particularly suitable for high-repetition rate, Q-switched operation. In preferred embodiment, reflectively passed initially only portion cross-sectional area first order compensation whereupon folded back one or more times along adjacent untraversed portions second additional averaging optical environment observed beam.
