EFFICIENT PASSIVE SWITCHES FOR NEODYMIUM LASERS MADE OF LIF:F2- CRYSTALS.

Academic Article

Abstract

  • PASSIVE Q SWITCHES HAVE BEEN MADE OF LIF CRYSTALS WITH F//2** - COLOR CENTERS. THESE SWITCHES ARE CHARACTERIZED BY A 14- TO 18-FOLD CONTRAST BETWEEN THE OPTICAL DENSITIES IN THE INITIAL AND BLEACHED STATES, AND THEY HAVE A HIGH INITIAL ABSORPTION COEFFICIENT OF 0. 6 CM** - **1. THE CHARACTERISTICS OF ONE-, TWO-, AND MULTIPULSE EMISSION REGIMES ARE OBTAINED FOR A YAG:ND**3** + LASER ( ″LAMBDA″ = 1. 064 ″MU″ ) WHEN LIF:F//2** - SWITCHES WITH DIFFERENT INITIAL TRANSMISSIONS WERE USED. THE EFFICIENCY IN THE Q-SWITCHING REGIME DEPENDS ON THE SWITCH TRANSMISSION AND AMOUNTS TO 50-70P OF THE EFFICIENCY UNDER FREE-OSCILLATION CONDITIONS PRODUCING PULSES WITH A PEAK OUTPUT POWER UP TO 4 MW. THE Q-SWITCHED RADIATION PULSES ARE OF 25 NSEC DURATION AND ARE CHARACTERIZED BY BOTH A HIGH AMPLITUDE AND A HIGH TIME STABILITY.
