LBO Crystal


He Rui optics'LBO crystal is one of the most versatile nonlinear optical crystal materials available. It has a very broad transmission range from vacuum UV to mid infrared, a very high damage threshold (actually the highest among the common nonlinear crystals) and is capable of noncritical phase matching (NCPM) in the near IR region, making it the material of choice for high power, high efficiency second harmonic generation (SHG) and optical parametric processes (OPO/OPA).
