ABOUT US
Gamdan Optics was founded by Dr. Sitai Lin, a veteran crystal grower, and was officially incorporated in 2006 primarily to grow LBO in the US. Since then, we have focused on delivering super low absorption optical crystals with UV-grade super-polished surfaces and high damage threshold coatings to achieve the highest lifetime and stability for the most demanding OEM applications world-wide.

OUR MISSION
GAMDAN Optic's mission is to enable high power visible and UV generation by consistently delivering top quality nonlinear optical materials, meeting or exceeding all customer specifications.
We understand the complexity and the critical nature of the materials that we handle. Our promise is to deliver reliable, best-performing parts at a competitive price.
With absolute focus on the most demanding applications, we have developed solutions specifically to excel in high peak and average power densities, deep into the UV.
USING HIGH QUALITY NONLINEAR CRYSTALS
We supply the highest quality LBO, BBO, KTP and Custom Doped YVO4 nonlinear crystals for a variety of uses.
GAMDAN Optic’s LBO crystals possess a high threshold for laser damage and have exceptional physical properties which makes them a great choice for green-blue UV conversion and fiber lasers. LBO crystals also have the highest damage threshold which reduces the likelihood of surface damages and distorted beams.
LBO crystals are often considered the most useful nonlinear optical crystal because of it’s large conversion rate and physical properties. You’ll find these used in medical applications, optical communication, and research and development. The best LBO has extremely low absorption of <10ppm/cm as measured by the Photo-thermal Common-path Interferometry. It’s three to five times less absorption than competing crystals with the same uniformity.
BBO crystals on the other hand have the highest conversion efficiency for UV. They also have a high damage threshold like LBO crystals which makes them operable in a variety of scenarios against significantly powered UV rays.
Our nonlinear optical crystal, BBO, has a wide transparency, broad phase-matching range, and hardness equivalent to 4.5. You’ll find these used in harmonic generators, spontaneous parametric down-conversion, and quantum linked photons.
Quality Confidence
People often ask us about our high quality optical crystals. They ask questions like, “How do you identify a high absorption crystal against another one?” or “What are the benefits of a high quality optical crystal?” These are great questions and a wide range of optical materials are used in optics so the explanation can get pretty complicated.
In order to consistently deliver top quality parts, GAMDAN Optics has established a Quality and Traceability system based on FDA and ISO guidelines. All products are tracked internally from synthesis to packaging. All fabrication procedures are documented and followed precisely by trained technicians. Documents are tracked internally and handled securely. All shipments come with an inspection report and traceability data. Internal quality control measurements are available upon request.
Customer Confidentiality
We understand the need of our customers to keep all design information confidential throughout the R&D and production processes. We have systems in places to make sure all customer information is handled securely and with the strictest discretion.
These factors all stress the importance of purchasing only high quality optical crystals. They possess the highest durability, damage threshold, and low absorption. Contact us today for more information.
