Generation of Shear Waves in a Soft Medium Using an OPO that Emits 2.1 μm Wavelength as Light Source

Martínez LO, Gonz&aa

Abstract

We present a scheme for conversion of pulsed light from 1.06 to 2.1 μm using a periodically poled ferroelectric crystal within a resonant cavity in which Optical Parametric Generation (OPG) nonlinear optical process occur when pumped with a pulsed Nd:YAG laser. This device emits 9 ns pulses of over 300 μJ and is a viable source for use with PhS-OCT system for generation of shear waves in a soft medium.
