Features:

• Large Effective Nonlinear Coefficient: BIBO crystal exhibits a nonlinear coefficient that is 3.5-4 times higher than that of LBO and 1.5-2 times higher than that of BBO. This makes BIBO an efficient material for nonlinear optical processes, particularly second harmonic generation (SHG).
• High Damage Threshold: BIBO crystal has a high damage threshold, allowing it to withstand high laser power without suffering damage. This characteristic makes BIBO suitable for use in high-power laser systems.
• Inertness to Moisture: BIBO crystal is inert to moisture, which means it does not degrade or lose its optical properties when exposed to humidity. This makes BIBO a more stable and reliable option for optical applications in various environments.

Applications:

• High power laser system: BIBO crystals are ideal for use in high-power laser systems due to their high damage threshold and their ability to withstand high-intensity laser beams without damage. This gives BIBO crystals a significant advantage in laser applications that require high energy output.
• Optical Parametric Oscillator (OPO): The application of BIBO crystals in optical parametric oscillators (OPOs) is particularly prominent. Compared with traditional nonlinear crystals, such as BBO and LBO, BIBO crystals have a larger allowable angle and a wider angular tuning range, which helps to achieve a wider tuning range and higher conversion efficiency. For example, in femtosecond optical parametric oscillators (fs-OPOs), BIBO crystals have been shown to be able to achieve higher photo-optical conversion efficiency and shorter pulse widths (Ref. 1)
• Optical Parametric Amplifier (OPA): Similar to OPO, BIBO crystals also have broad application prospects in optical parametric amplifiers (OPAs). Its high nonlinearity coefficient and wide transmittance band make BIBO crystals excellent in signal amplification and frequency conversion.
• Frequency Conversion:BIBO crystals are ideal SHG (Second Harmonic Generation) crystals to generate blue laser output. Its high nonlinearity coefficient makes the frequency conversion process more efficient, resulting in a higher quality blue laser beam.
• Laser processing and material handling: In the field of laser processing and material handling, the high power capability of BIBO crystals makes them a key component in the manufacture of high energy density laser beams. These laser beams can be used in a variety of industrial applications such as cutting, welding, perforating, and more.
• Scientific research and development: BIBO crystals also play an important role in scientific research and development. Its excellent nonlinear optical performance provides new tools and possibilities for ultrafast phenomenon research, strong field physics, biomedical imaging and other fields
