An organic l-Arginine phosphate monohydrate (LAP) crystal showed a much lower stimulated Brillouin scattering (SBS) threshold at 1.06-μm wavelength than fused silica and a higher SBS reflectivity of approximately 65%, which is limited because of its absorbance. The reason LAP crystal has a high damage threshold at Q -switched pulse operation is due to SBS backward reflectance. The LAP crystal is interesting not only as a frequency converter but also as a phase-conjugated SBS mirror for all solid-state high-energy lasers because of its high SBS gain coefficient.
