Overview
Raicol has pioneered the development of High Gray Track Resistance KTP crystals, setting a benchmark in the field of nonlinear optics. Our innovative crystal growth technique enhances the high power density capabilities of KTP while leveraging its remarkable Second Harmonic Generation (SHG) coefficient.
Gray tracks in KTP crystals are a consequence of induced color centers, which result in broad optical absorption within the visible and near-infrared wavelengths. These gray tracks typically form when the crystal is exposed to high average power pulsed lasers or continuous wave (CW) laser irradiation. This cumulative process can lead to a deterioration in the crystal’s transparency and its ability to effectively convert harmonics.
By addressing the challenges posed by gray track formation, Raicol’s High Gray Track Resistance KTP crystals ensure improved durability and performance under high-power laser conditions, making them an optimal choice for advanced laser applications.
