Ti:Sapphire Crystals Produced for the Requirements of Your Unique Laser Architecture
Ti:Sapphire crystals are grown using the Heat Exchanger Method, (HEM). This unique method of growth allows for production of the world's largest Ti:Sapphire crystals, with excellent optical and thermal properties. The growth of our crystals takes place in a reducing atmosphere in order to maximize Ti3+ ions, thereby reducing parasitic absorption and maximizing FOM (Figure of Merit) values. The superior homogeneity and low wave front distortion of our laser rods allow laser systems to reach high energy levels without sacrificing beam profile quality. Current production of amplifier crystals of over 200 mm in diameter are ensuring success at the next generation of high intensity laser facilities.
High quality Ti:Sapphire laser crystals begin with perfect crystalline structure and the correct 3+ valance electron state. We ensure these requirements through our multiple-stage, rigorous inspection process, using state-of-the-art test and measurement equipment. We test our rods for absorption values, homogeneity, light scatter, FOM, flatness, and transmitted wave fronts. Each HEM laser rod is examined and verified utilizing advanced equipment and expert laser technicians. Total focus on quality and accuracy guarantees that our laser crystals dimensions, surfaces and crystalline structure provide the foundation for your laser platform’s high power levels and excellent beam profiles.
Features of HEM® Ti:Sapphire:
HEM Ti:Sapphire's wide emission range, (660 nm to 1180 nm), high-power density pumping capability along with excellent crystalline structure enable today’s high intensity laser platforms. The high intensity platforms utilize Ti:Sapphire because of high peak-power, short pulses, increasing repetition rates and excellent beam quality and control. These facilities are creating the next generation of laser based applications such as radio therapy, proton therapy, accelerator physics, nuclear physics, infrared spectroscopy and materials characterization. GT Crystal Systems works closely with its customers to promote new designs and technology for the advancement of high intensity lasers.
