Request InfoRaicol Crystals Ltd.ROSH HAAYIN, Israel, Feb. 13, 2018 — SKTP flux-grown Potassium Titanyle Phosphate (KTP) crystals from Raicol Crystals Ltd. are High Gray Track Resistance flux grown KTP crystals, enabling a higher average power density for the second-harmonic generation of 1000- to 1400-nm laser sources. When a crystal is subjected to high-power, high-repetition rate laser pulses or continuous wave laser irradiation, gray tracks are often produced. These gray tracks occur because of induced color centers in the KTP crystal that have broad optical absorption in the VIS and NIR wavelengths, especially at 532 nm. The process of the gray track...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra October 2022 IssueExplosion-Proof TDL SpectrometerAn explosion-proof TDLS8200 probe-type tunable diode laser spectrometer from Yokogawa Electric Corp. provides simultaneous measurement of oxygen and carbon monoxide or methane concentrations for...Photonics.com 2/13/2023Swept Tunable LaserThe Laser 2000 series swept tunable laser from Quantifi Photonics Ltd. is a compact, laboratory-grade device that can be operated as a step-tuned, swept-wavelength, or fixed-wavelength...Photonics.com 11/23/2023Handheld Laser RangefinderThe LMS-RF-NC-6025-NI-01 from LumiSpot Tech is an uncooled handheld rangefinder that uses infrared technology for target acquisition and images in both infrared and a color TV mode.
