High Damage Threshold: LBO crystals have the highest damage threshold of all commonly used inorganic nonlinear optical crystals. For example, under a 1053nm laser with a pulse duration of 1.3 ns, the damage threshold can reach 18.9 GW/cm² . This property makes LBO crystals particularly suitable for high-power laser systems, where they can withstand higher laser energies without damage.
Wide Transmission Band: LBO crystals have a very wide optical transmission range, from the deep ultraviolet band (about 160 nm) to the infrared band (about 2600 nm) . This feature enables LBO crystals to be suitable for a wide range of wavelength laser systems to meet the needs of different fields.
High Optical Uniformity: The LBO crystal has good optical uniformity and no internal envelope, which helps to ensure the quality of the laser beam and reduce beam distortion and defocus. Its optical uniformity can reach δN≈10-6/cm
Larger effective nonlinearity coefficients: The effective SHG coefficient of LBO crystals is larger, about three times that of KDP crystals . This means that under the same conditions, the LBO crystal is able to achieve frequency conversion more efficiently and output higher power lasers.
Wide angle reception with small walk-out angle: LBO crystals have a wide reception angle and a small walk-away angle, which makes it easier to achieve phase matching and improve frequency conversion efficiency in nonlinear optical processes.
Thermal Stability: LBO crystals are known for their excellent thermal stability, being able to withstand large amounts of heat when processing high-power lasers without causing any significant loss of performance.
Applications: High Power Laser Systems, Nonlinear Optical Processes, Ultraviolet and deep ultraviolet lasers, etc.
