A DIODE-PUMPED Yb:YAG DISK LASER UTILIZING A COMPOUND PARABOLIC CONCENTRATOR

摘要

PURPOSE: A diode-pumped Yb:YAG Lasers using a compound parabolic concentrator is provided to increase the absorbing efficiency of a diode array pumped beam by focusing a pumped beam of a diode array of high output to the compound parabolic concentrator. CONSTITUTION: A diode-pumped Yb:YAG Lasers is formed with a stacked diode array(4), a pumped beam focusing lens(6), a resonator mirror(8), a reflective mirror(10), a compound parabolic concentrator(12), a cooling portion(14), and a laser output portion(16). The stacked diode array(4) emits a pumped beam of hundreds or thousands watts. The pumped beam focusing lens(6) is used for focusing the pumped beam. The resonator mirror(8) is located at a predetermined interval from the pumped beam focusing lens(6). The reflective mirror(10) is used for refracting the pumped beam passing the resonator mirror. The compound parabolic concentrator(12) is used for absorbing and reflecting the pumped beam refracted by the reflective mirror(10). The cooling portion(14) fixes the compound parabolic concentrator(12) and performs a cooling function. The laser output mirror(16) is used for oscillating a laser beam.
