摘要：PURPOSE:To reduce a necessary shift amount of a control block and to enhance an oscillation efficiency by a method wherein a prism-shaped total reflector is installed on a light path of a lar reso地包天怎么办
星巴克咖啡图片nator, a mirror surface of the control block ud to control a reflection by being brought into contact with a reflecting surface is attached or detached by using an actuator and an incidence angle of a lar beam is t to be larger than 45 deg.. CONSTITUTION:A control block 3 is raid; a mirror surface 3a is brought into contact with a reflecting surface 2 of a total reflector 1; a lar beam 7 is incident in parallel with the reflecting surface 2 from a cant face 1a. Then, the control block 3 is lowered by using the actuator 4; the mirror surface 3a is parated suddenly from the reflecting surface 2. When a distance from the reflecting surface 2 is at about 0.4 time a lar oscillation wavelength, a Q of a resonator becomes sufficiently high and a lar oscillation is started. Through this constitution, it is possible to reduce a shift amount, of the control block 3, required to obtain a reflection factor of 100% of the lar beam at the reflecting surface 2 and to supplement a shortage of a shift speed.写给爷爷的一封信
