Product Info
Raicol is the first to develop High Gray Track Resistance flux grown KTP crystals, enabling a higher average power density for the second-harmonic generation (SHG) of 1000-1400 nm laser sources.
When a crystal is subjected to high power, high repetition rate laser pulses, or CW laser irradiation, gray tracks are often produced.
These gray tracks occur due to induced color centers in the KTP crystal that have broad optical absorption in the visible and near infrared wavelengths, especially at 532 nm.
The process of the gray track formation is cumulative, and leads to deterioration of harmonic conversion.
Raicol’s new SKTP crystal allows for use at a high power density, while also providing effective gray track resistance to eliminate the gray track effect.
