Subnanosecond ellipticity detector for laser radiation

Thermopile detector of light ellipticity

Polarimetric imaging is widely used in applications from material analysis to biomedical diagnostics, vision and astronomy. The degree of circular polarization, or light ellipticity, is associated with the S3 Stokes parameter which is defined as the difference in the intensities of the left- and right-circularly polarized components of light. Traditional way of determining this parameter relies...

Laser Damage Study With Subnanosecond Pulses

This report describes a ruby laser test facility for conducting laser-Induced damage experiments with single subnanosecond IISBE. The facility includes a laser damape monitoring system and a mode-locked oscillator-amplifier system with pulse selection.

Fast Gate: Subnanosecond Gated Detectors for Laser Radiography

Subnanosecond, time-resolved, broadband infrared spectroscopy using synchrotron radiation

A facility for subnanosecond time-resolved ~pump-probe! infrared spectroscopy has been developed at the National Synchrotron Light Source of Brookhaven National Laboratory. A mode-locked Ti:sapphire laser produces 2 ps duration, tunable near-infrared pump pulses synchronized to probe pulses from a synchrotron storage ring. The facility is unique on account of the broadband infrared from the syn...

Subnanosecond Pulse Measurements of 10.6 gm Radiation with Tellurium

Subnanosecond infrared pulses have been measured by nonc011inear secondharmonic generation in tellurium. The method is very practical because due to the high refractive index the fine tuning of the phase matching is easily obtained by rotating the crystal around the optic axis.
