FREQUENCY STABILIZATION He-Ne LASER CONTROLLABLE WITHIN WIDE TEMPERATURE RANGE

摘要

PROBLEM TO BE SOLVED: To provide a frequency stabilization laser equipment where a frequency stabilization laser is highly stabilized, a range of working temperature is expanded, and a high accurate stabilization is easily realized.;SOLUTION: A correction apparatus is constructed in such a manner that a composite amplifier is made up by combining a sine wave oscillator whose amplitude is variable, an operational amplifier where an offset is little, and a voltage limiter having an exact limit voltage; and an output of the composite amplifier is integrated. In order to expand a range of environmental temperature at which the high accurate stabilization laser equipment can withstand, two similar correction apparatuses are used.;COPYRIGHT: (C)2007,JPO&INPIT
