Title: Method for decreasing light scattering body in beta barium borate single crystal, wavelength conversion element and laser apparatus
Inventor: KOUDA HIKARI
IPC: G02F1/37
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To decrease the light scattering bodies in a beta barium borate (BBO) single crystal, to improve the deterioration resistance characteristic of a BBO wavelength conversion element and to improve its long-term reliability by heat treating the BBO single crystal at a specified temp. of a specific range. SOLUTION: This method for decreasing the light scattering bodies in the BBO single crystal consists in heat treating the BBO single crystal at the specified temp. of 800 to 925 deg.C. More preferably, the heat treatment is executed for >=30 hours. The crystal contg. the light scattering bodies is heat treated in a resistance heating furnace of <=925 to >=800 deg.C below the phase transition of an α-β phase, by which the light scattering body components are gradually aligned to the bearings of the surrounding crystals and, therefore, the decrease of the light scattering bodies is made possible. The decreasing effect by the heat treatment is high as the crystal bearings of the light scattering bodies vary just slightly from the intrinsic crystal bearings in the case of the crystal 8 pulled up and grown in the bearings of 110, 100.  As a result, the laser destruction threshold characteristic, long-term reliability, output rising characteristic, etc., of the BBO element are greatly improved.

Abstract: PURPOSE:To obtain a conduction control circuit for a small-sized low-cost motor by providing conduction control means for stopping energization of the motor for a predetermined time when a motor current exceeding a reference value is detected and restarting after a predetermined time is elapsed. CONSTITUTION:A one-shot multivibrator 5 is arranged between a conduction stop transistor Q2 and a comparator 3 to turn ON the comparator 3 by inversion when a motor current I is increased when a motor 1 is started to exceed a reference current thereby to operate the multivibrator 5, thereby turning ON the transistor Q2 during an operating time. After an OFF operation delay time is elapsed, a control transistor Q1 is turned OFF, the motor current I flows through a flywheel diode 4 during the operating time of the multivibrator 5 to be reduced. When the operating time is elapse, the transistor Q2 is turned OFF, and the current I again flows after an ON delay time. As a result, a control element can be reduced in capacity and the circuit can be reduced in size.
