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.

This limited warranty covers defects in materials and workmanship under normal use and service, when the product is installed, operated, and maintained according to Vigitek documentation or written instructions. Warranty coverage begins on the date of shipment or delivery (unless otherwise stated in writing).

Not Covered

Normal wear and tear, cosmetic damage, or consumable parts (if applicable).
Damage caused by misuse, abuse, accidents, improper handling/storage, improper installation, or operation outside published specifications.
Damage caused by electrical issues (incorrect voltage, wiring errors, power surges), environmental conditions beyond the product rating, or inadequate cooling/ventilation.
Failures resulting from unauthorized modifications, firmware changes, tampering, or repair/service performed by anyone not authorized by Vigitek.
Integration issues with third-party components or systems, unless explicitly included in the written scope for a supplied system.
Downtime, lost profits, or other indirect/incidental/consequential damages (to the extent permitted by law).
Labor for removal/reinstallation, on-site service, and shipping/freight unless explicitly stated in writing.

How To Request Warranty Service

Please contact us to obtain a Return Authorization (RA) before sending any product/part back for evaluation.

Email: sales@vigitek.biz
Phone: +1 (203) 829-5756
