CavityFilters
For Solid-State Lasers
|
KIGRE INC.'s expertise in laser glass technology has led the way in the company's development of a wide range of cavity filter glass for solid-state lasers. Filters are used inside the laser cavity to enhance beam amplification by matching the frequency of the wavelengths corresponding to the appropriate pump bands. They also absorb unwanted UV and IR radiation. KIGRE'S filters are strengthened after fabrication using a proprietry method which tempers the filter with approximately five times the strength of normal glass. This added strength extends the operational life and makes possible more precise boring and machining. KIGRE manufactures filters in a wide variety of sizes and configurations, ranging from simple flow tubes and slides to complete cavity assemblies with barium sulphate overcoating. In addition, KIGRE also develops custom filters for a wide range of applications. |

Filters for improved laser Efficiency
KSF - 5/KSF - 10 Samarium Filters
KIGRE’S Samarium filters are made from KSF filter material. Developed by KIGRE, this material is a high transmission, high strength glass doped with samrium and sensitizer ions. KSF-5 has 5% samari um doping; KSF-10 has 10% samrium doping. KSF absorbs one micron and unwanted UV and IR radiation while transmitting and reingorcing at wavelengths corresponding to the neodymium pump bands. KIGRE’s KSF filter are manufactured in a variety of sizes and configurations.s These configurations range from simple flow tubes and slides to complete cavity assemblies with barium sulphate overcoating. An added benefit-KSF filters are strengthened after fabrication using a proprietary method wich tempers the filter with approximately five times the strength of mormal glass.
KF-2
KF-2 filter material is ideal for improving the efficiency of glass laser systems. KF-2 is available in a number of size and configurations. CUT-OFF POINT (2% Transmission 2mm sample)…. 300 Nanmeters
KC-331
KC-331 was developed especially for use with easily solarized UV-sensitive materials such as Alexandrite. As an added feature, KC-331 contains properties which make it radiation resistant. CUT-OFF POINT (2% Transmission 2mm sample)…. 347 Nanmeters
