High energy single pulse laser calorimeter

摘要

A single pulse laser calorimeter apparatus utilizing the high laser output pulse to measure the energy output of the laser. The output energy of the laser is absorbed in a NG-1 type glass panel and is transformed into heat. The heat is transferred to an aluminum back plate which is epoxied to the glass and is detected by a series of forward biased p-n junction diodes that are epoxied to the aluminum plate. The voltage drop across the diodes is monitored with a high impedance measuring device such as a strip chart recorder or A/D converter.
