CTH:YAG
Cr:Tm:Ho:YAG (CTH:YAG) is an excellent crystal that emits 2.1μm wavelength laser and is widely used in medical, military and meteorological fields. WISOPTIC uses high-purity raw materials and sophisticated technology to produce high-quality CTH:YAG crystals. This crystal is capable to output high pulse energy and is suitable for repetitive frequency operation. WISOPTIC provide laser rods with diameters of 3 to 6 mm and lengths of 50 to 120 mm.
Features of CTH:YAG
-High slope efficiency, room temperature operation
-Suitable for lamp pumping or LD pumping
-Safe for human eyes

Er:YAG Crystal
Erbium Doped Yttrium Aluminum Garnet (Er:YAG) lases at 2940 nm which is the same as hydroxyl absorption peak. Therefore the rays produced by Er:YAG can be strongly absorbed by biological tissues which make Er:YAG lasers being widely used in medical area, such as dental (hard tissues), orthopedics, etc. Er:YAG produced by WISOPTIC has high quality of good internal optical uniformity and high slope efficiency. -
Cr4+:YAG Crystal
Chromium Doped Yttrium Aluminum Garnet (Cr4+: YAG) is an excellent material for passively Q-switching diode pumped or lamp-pumped Nd:YAG, Nd:YLF, Nd:YVO4 or other Nd/Yb doped lasers at wavelength 0.8~1.2 μm. Cr4+: YAG might replace traditional material, such as LiF, organic Dye and color centers due to its advantages such as: being chemically stable, durable, UV resistant, having good thermal conductivity and high damage threshold (＞500 MW/cm2 ), and being easy to be operated. WISOPTIC provides Cr4+:YAG with Cr4+ doping level of 0.5~3 mol% and with cross sections from 2 × 2 mm2 to 14 × 14 mm2 and length from 0.1 mm to 12 mm. The initial transmission is 10% ~92% according to customers' requirements. -
Periodically Poled Lithium Niobate (PPLN)
WISOPTIC provide high quality LN crystals including: pure LiNbO3, MgO:LN, Periodically Poled Lithium Niobate (PPLN), and MgO:PPLN. The doping ratio of MgO is typically 5%. WISOPTIC's PPLN could be used at 460-5100nm, and the polarization period is 4.0-35μm. These PPLN crystals in various sizes and period could be coated and mounted according to customer's request. WISOPTIC also provide heater/oven (heating type: heating resistance) and temperature controller for PPLN. -
High Quality LBO Crystal with Large Aperture and High LDT
LBO (LiB3O5) is a kind of non-linear optical crystal with good ultraviolet transmittance (210-2300 nm), high laser damage threshold and large effective frequency doubling coefficient (about 3 times of KDP crystal). So LBO is commonly used to produce high power second and third harmonic laser light, especially for ultraviolet lasers. -
High Quality LN Crystal (LN Pockels Cell) Used in 1064nm Laser System
LiNbO3 (Lithium Niobate) crystal is a multifunctional material that integrates properties of piezoelectric, ferroelectric, pyroelectric, nonlinear, electro-optical, photoelastic, etc. LiNbO3 has good thermal stability and chemical stability. Periodically Polarized Lithium Niobate (PPLN) is a highly efficient wavelength conversion non-linear crystal with wide light transmission range (0.4-4.5 µm) covering the near and mid-infrared regions, long service life, and can be used for frequency doubling, beat frequency, sum frequency, optical parametric oscillation and optical parametric amplification, etc.

WISOPTIC provide GTR-KTP developed by hydrothermal method
KTP (KTiOPO4 ) is one of the most commonly used nonlinear optical materials. For example, it’s regularly used for frequency doubling of Nd:YAG lasers and other Nd-doped lasers, particularly at low or medium-power density. KTP is also widely used as OPO, EOM, optical wave-guide material, and in directional couplers. -
High electric resistivity KTP Pockels cell
HGTR (high anti-grey track) KTP crystal developed by hydrothermal method overcomes the common phenomenon of electrochromism of the flux-grown KTP, thus has many advantages such as high electrical resistivity, low insertion loss, low half-wave voltage, high laser damage threshold, and wide transmission band. -
High quality LBO crystal not must be expensive
LBO (LiB3O5) is a kind of non-linear optical crystal with good ultraviolet transmittance (210-2300 nm), high laser damage threshold and large effective frequency doubling coefficient (about 3 times of KDP crystal). So LBO is commonly used to produce high power second and third harmonic laser light, especially for ultraviolet lasers. -
Why your Nd:YAG failed to make enough energy
Nd:YAG (Neodimium Doped Yttrium Aluminum Garnet) has been and continue to be the most widely used laser crystal for solid-state lasers. Good fluorescence lifetime (twice more than that of Nd:YVO4) and thermal conductivity, as well as robust nature, make Nd:YAG crystal very suitable for high-power continuous wave, high-energy Q-switched and single mode operations. -
