What is Laser crystal optical components

Hyperion Optics provides optical components, including laser crystals for a wide range of laser, semiconductor, military, space and fiber optics applications. We work on high power visible and UV light generation by delivering high quality nonlinear products reaching our customer specifications.

Our crystals solution includes BBO, BIBO, KTP, anti gray tracking KTP, LiNbO3, Nd YAG crystal and wafer and much more. With 1/10 lambda precision, coated/un-coated options, competitive pricing.

KTP crystal is mostly used as nonlinear crystals for frequency doubling of solid-state Nd:YAG crystal or Nd:YVO4 crystal laser, as it has large nonlinear optical coefficients, wide angular bandwidth and small walk-off angle, broad temperature and spectral bandwidth. KTP crystal also has high electro-optic(E-O) coefficient and low dielectric constant, and large figure of merit, these features make it also widely used in electro-optic application.

Advantages of KTP Crystal:

• Large Nonlinear Optical (NLO) Coefficients
• Wide Angular Bandwidth and Small Walk-off Angle
• Broad Temperature and Spectral Bandwidth
• High Electro-Optic (E-O) Coefficient and Low Dielectric Constant
• Large Figure of Merit for an Optical Waveguide Modulator
• Nonhygroscopic, Good Chemical and Mechanical Properties

There are mainly three types of crystals:

KTP Crystal

BBO Crystal

The BBO Crystal is a high-temperature phase of BaB2O4, is an excellent birefringent crystal an efficient NLO crystal for the second, third and fourth harmonic generation of Nd: YAG lasers, and the best NLO crystal for the fifth harmonic generation at 213 nm. Conversion efficiencies of more than 70% for SHG, 60% for THG and 50% for 4HG, and 200 mW output at 213 nm (5HG) have been obtained, respectively. BBO Crystal has been widely used in 2,3,4 or 5 harmonic generations for high power visible/UV sources, and optical parametric conversions for high power broadly tunable sources.

Advantages of BBO Crystals

• Broad phase-matching range from 409.6 nm to 3500 nm
• Extensive optical transmission from 190 nm to 3500 nm
• Large effective second-harmonic-generation (SHG) coefficient
• High damage threshold of 10 GW/cm2 for 100 ps pulse-width at 1064 nm
• Wide temperature-bandwidth of about 55℃
• Excellent mechanical and physical properties

YAG Crystal

Undoped YAG Crystal is an excellent material for UV-IR optical windows, particularly for high temperature and high energy density applications. The mechanical and chemical stability is comparable to sapphire crystal, but YAG is unique with non-birefringence and available with higher optical homogeneity and surface quality. Up to 3 YAG boule grown by CZ method, as-cut blocks, windows and mirrors are available from CryLight.
