Apparatus and method for stabilizing an ultrashort optical pulse amplifier

摘要

An apparatus for maintaining the temperature stability of an amplifier system comprises a device for heating, cooling or heating an cooling one or more sub-assemblies of the amplifier system, a temperature sensor for detecting variations in temperature of a sub-assembly, and a controller operably connecting the two. The signal from the sensor is used by the controller to adjust the amount of heating, cooling, or heating and cooling of a sub-assembly in order to maintain its temperature within a range sufficiently small to ensure stable performance.
