6.1   INTRODUCTION

The stimulated Brillouin scattering (SBS) effect in various liquids and gases can be
applied to a phase conjugator [1, 2], as described in previous chapters. In SBS liquid
media such as heavy fluorocarbons [3–5] and tetrachlorides, it is necessary to
eliminate the dissolved impurities and solid microparticles, and these media must be
carefully handled due to their toxic properties. Quartz was used as a nonlinear
medium in the first practical demonstration of SBS in 1964 [6]. The first observation
of SBS in an optical fiber indicated that fiber provides highly reflective SBS due to
its long interaction length [7]. Long path lengths can produce SBS even at a low
incident power [8–11]. However, the incident pulse energy must be limited to a few
millijoules to avoid surface damage of the fiber.

Organic L-arginine phosphate monohydrate (LAP) was examined in 1983 at
Shangdon University, China as a nonlinear optical material [12]. LAP appeared to
be a promising material for laser fusion experiments as a replacement for potassium
dihydrogen phosphate (KDP) crystal [13, 14]. LAP and its deuterated analog,
DLAP, have some attractive properties...

Products & Services
Lasers
Lasers are devices that produce intense beams of monochromatic, coherent radiation. The word "laser" is an acronym for Light Amplification by Stimulated Emission of Radiation.
Diode Lasers
Diode lasers use light-emitting diodes to produce stimulated emissions in the form of coherent light output. They are also known as laser diodes.
Ion Lasers
Ion lasers function by stimulating the emission of radiation between two levels of an ionized gas. They provide moderate to high continuous-wave output of typically 1 mW to 10 W.
Helium Neon Lasers
Helium neon (HeNe) lasers have an emission that is determined by neon atoms by virtue of a resonant transfer of excitation of helium. They operate continuously in the red, infrared and far-infrared regions and emit highly monochromatic radiation.
Helium Cadmium (HeCd) Lasers
Helium cadmium (HeCd) lasers are relatively economical, continuous-wave sources for violet (442 nm) and ultraviolet (325 nm) output. They are used for 3-D stereolithography applications, as well as for exposing holographs.
