HGTR-KTP Crystals for EO Applications
High anti-grey stain performance: HGTR-KTP crystals have up to 5 to 10 times more resistant to ash stains than KTP crystals grown by ordinary molten salt method by using advanced process methods such as unique flux and heat treatment technology. Once the gray stain is formed, it will absorb a large amount of light energy from the propagating beam, resulting in problems such as device heating, reduced frequency doubling efficiency, and reduced laser output power. The high anti-gray properties of HGTR-KTP crystals enable them to be used stably for long-term and stable application in the frequency conversion of high-power lasers.
High optical quality: The HGTR-KTP crystal has high transmittance and low absorption coefficient, with extremely low absorption coefficient at 1064 nm and 532 nm wavelengths, ensuring high optical quality. At the same time, its optical uniformity and parallelism have also reached a high level, which is suitable for making high-precision electro-optical modulators and other EO devices.
High Damage Threshold: HGTR-KTP crystals have a high laser damage threshold and are able to withstand high power density laser irradiation without damage. This makes it promising for a wide range of applications in high-power laser systems.
Excellent thermal and mechanical properties: HGTR-KTP crystals have high thermal conductivity and good mechanical stability, and can maintain stable performance in high temperature and high stress environments. This is especially important for making EO devices that operate in high-temperature environments.
Wide range of applications: Due to its excellent performance, HGTR-KTP crystals are widely used in laser frequency doubling, sum frequency, differential frequency, parametric oscillation, optical waveguide devices, electro-optical modulators and other EO applications. These applications cover a wide range of fields, including military scientific research, medical, ocean insight, laser weapons, and environmental remote sensing monitoring.
Applications: Electro-optical modulator, Laser frequency multiplier, etc.
