Description

HGTR-KTP Non-Linear Crystal is an excellent nonlinear optical material with a decisive edge: gray track resistance sufficiently greater than typical flux grown KTP. Gray tracking is the slow degradation that clouds ordinary KTP under intense light. HGTR-KTP resists it. The material is potassium titanyl phosphate, grown for high gray-track resistance.

What gray tracking does

Under sustained high-intensity light, ordinary KTP can develop gray tracks: faint absorbing paths that grow with exposure. They steal conversion efficiency and distort the beam. A crystal with high gray-track resistance keeps performing where standard material fades. In other words, the crystal stays clear where ordinary KTP would darken.

HGTR-KTP Non-Linear Crystal advantages

The damage threshold is high and conversion efficiency is high. Absorption stays low and homogeneity is high. Electrical conductivity is low. Together, these traits make the crystal extremely suitable for both commercial and military lasers. High homogeneity means the conversion stays uniform across the full aperture. Low absorption keeps thermal effects small. Consequently, the output stays stable over long runs.

Where it works

Laboratory and medical systems use it. Range-finders and lidar rely on its stable doubling. Optical communication and industrial systems round out the list.

HGTR-KTP Non-Linear Crystal handling and stability

The crystal is chemically and mechanically stable. It stores and handles like standard KTP, with no special precautions beyond normal optical care.

Typical applications

Second harmonic generation for frequency doubling is the core job. Optical parametric oscillators extend the wavelength reach. Electro-optic Pockels cells use its E-O response. Quasi-phase-matched structures benefit from its uniformity. Also, research labs use it for stable long-term experiments. For the standard grade, see our KTP Non-Linear Crystal.
