Description

Key Advantages
Broad Transparency Range
Exhibits excellent transparency from the deep ultraviolet (UV) to the mid-infrared (IR) spectrum, enabling frequency conversion across a wide range of laser wavelengths. This versatility supports applications from UV harmonic generation (e.g., 266 nm from 1064 nm) to IR pulse manipulation.
Wide Phase-Matching Bandwidth
Supports non-critical and critical phase matching over a broad wavelength range, allowing efficient harmonic generation (up to 5th harmonic) for diverse laser sources, including Nd-doped crystals, titanium sapphire, Yb-doped lasers, and dye lasers.
High Nonlinear Optical Coefficients
Boasts strong nonlinearity, facilitating efficient conversion of fundamental laser frequencies to higher harmonics (e.g., doubling 1064 nm to 532 nm, tripling to 355 nm). This efficiency reduces power loss and enhances output stability in high-power laser systems.
Exceptional Damage Threshold
Withstands intense laser pulses (750 MW/cm2 at 1064 nm, 10 ns, 10 Hz), making it ideal for high-energy pulsed lasers and ultrafast systems where material durability is critical to prevent optical damage.

Applications
Harmonic Generation in Nd-Doped Lasers
Efficiently generates up to the 5th harmonic of Nd:YAG, Nd:YVO?, and other Nd-doped lasers (e.g., 1064 nm ?? 532 nm (2nd), 355 nm (3rd), 266 nm (4th), 213 nm (5th)), enabling applications in UV spectroscopy, micromachining, and lithography.
Frequency Conversion for Pulsed Lasers
Used for second- and third-harmonic generation in titanium sapphire (Ti:sapphire), Yb-doped, and dye lasers, expanding their wavelength capabilities for research (e.g., ultrafast spectroscopy) and medical procedures (e.g., precision laser surgery).
Ultrashort Laser Pulse Characterization
Essential for techniques like FROG (Frequency-Resolved Optical Gating), XFROG (Cross-Correlation FROG), SPIDER (Spectral Phase Interferometry for Direct Electric-Field Reconstruction), and dispersion/chirp scanning, enabling detailed analysis of femtosecond and picosecond pulses.
