End-pumping system for a diode pumped solid state laser and solid state laser
Original language description
The present invention relates to an end-pumped system for efficiently pumping a laser active medium. The system comprises a laser diode stack emitting an optical beam, equipped with a fast axis collimator that defocuses the fast axis of the optical beam. A lens duct with a tapered shape and flat input and output surfaces is coupled to the diode stack. The input side of the lens duct covers the entire area of the diode stack, preventing pump beam escape through total internal reflection on its side surfaces. The system further includes a laser active medium, coupled to the output side of the lens duct. The invention enables precise control of pump beam divergence angles and can incorporate various materials for the lens duct, including borosilicate crown glass, fused silica, calcium fluoride, zinc selenide, germanium, undoped YAG, polymethyl methacrylate, or sapphire. Applications of the system include solid-state lasers and its utilization as a part of laser amplifiers and oscillators, offering enhanced performance and efficiency in laser technologies.
