Press Release: ARSS Patent Granted
GAMDAN Optics has been awarded U.S. Patent No. 12,360,432 for its ARSS nanostructured surface, a coating-free anti-reflective technology etched directly into nonlinear optical crystals. The result: transmission above 99.5% and laser damage thresholds up to 5x higher than conventional AR coatings.
GAMDAN Optics Opens Second San Jose Facility to Expand Crystal Growth and Fabrication Capacity
GAMDAN Optics has opened a second facility in San Jose, California, expanding capacity across both crystal growth and in-house fabrication. The added space lets the U.S. manufacturer grow more material and finish more components on-site — shortening lead times and supporting higher-volume production for its defense, fusion energy, quantum computing, and industrial laser customers.
GAMDAN Optics Presents Seamless & Scalable Method for Large Aperture LBO
Large-aperture laser materials such as crystalline gain media and nonlinear optical crystals are essential for the success of high-energy lasers, but attractive crystals, such as LBO, are often not available in large enough sizes. An optically seamless and inherently scalable process for aperture enlargement is reported here.
GAMDAN Optics, Inc. Advances KGW Crystal Development
San Jose, CA, USA — November 3, 2025 — GAMDAN Optics is pleased to announce significant progress in the growth and characterization of undoped KGW (Potassium Gadolinium Tungstate) crystals, optimized for Raman shift applications in ultrafast laser systems.
White Paper - Nonlinear Crystal Selection and Specification
A key task faced by engineers using nonlinear crystals is the correct selection and effective specification of the appropriate NLO crystal for a particular laser design or application. GAMDAN Optics supports customers in successfully completing all the steps in this selection and specification process.
White Paper - Walkoff in Nonlinear Optics
Scientists and engineers working with nonlinear crystals must understand and consider dispersion and walkoff when calculating phase matching conditions, conversion efficiencies, and beam propagation dynamics in nonlinear optical processes such as second-harmonic generation (SHG), sum-frequency generation (SFG), and parametric down-conversion (PDC).
