Abstract

An optical transconductance varistor system having a modulated radiation source configured to provide modulated stimulus, a wavelength converter operably connected to the modulated radiation source to produce a modulated stimulus having a predetermined wavelength, and a wide bandgap semiconductor photoconductive material in contact between two electrodes. The photoconductive material is operably coupled, such as by a beam transport module, to receive the modulated stimulus having the predetermined wavelength to control a current flowing through the photoconductive material when a voltage potential is present across the electrodes.

Method and system for processing optical materials for high power laser systems

Patent Demos, Stavros G; Raman, Rajesh; Negres, Raluca A

A method of determining conditioning pulse parameters for an optical element includes directing a pump pulse to impinge on the optical element and directing a probe pulse to impinge on the optical element. The method also includes determining a first time associated with an onset of electronic excitation leading to formation of an absorbing region of the optical element and determining a second time associated with expansion of the absorbing region of the optical element. The method further includes defining a turn-off time for a conditioning pulse between the first time and the second time. According to embodiments of themore » « less

System and method for laser-based, non-evaporative repair of damage sites in the surfaces of fused silica optics

Patent Adams, John J.; Bolourchi, Masoud; Bude, Jeffrey D.; ...

The present disclosure relates to a system for repairing a damage site on a surface of an optical material. The system may have an Infrared (IR) laser which generates a laser beam having a predetermined wavelength, with a predetermined beam power, and such that the laser beam is focused to a predetermined full width ("F/W") 1/e.sup.2 diameter spot on the damage site. The IR laser may be controlled to maintain the focused IR laser beam on the damage site for a predetermined exposure period corresponding to a predetermined acceptable level of downstream intensification. The laser beam may heat the damagemore » « less
