Diamond is an excellent crystalline Raman material, with the largest Raman frequency shift of 1332.3 cm-1 among known crystalline materials, and a Raman gain linewidth of approximately 1.5 cm-1 at room temperature. The ultra fast heat dissipation capability enables diamond crystals to maintain high Raman gain unchanged under high-power operation and obtain high-quality laser output.
