Integrating Chinese Technology with American Ideals

New YAG Substrate for Laser Applications
Useful for Both UV and Infrared Optics

Introduction

Substrates are necessary material for high powered laser and optical applications. Substrate windows are key to a laser beams effectiveness and power output.An unreliable substrate equals an unreliable laser / photonics device. Our scientists have developed a reliable material for such applications.

Our Technology

Undoped YAG is a new substrate and window material that can be used for both UV and IR optics. It is particularly useful for high temperature and high energy applications.YAG shows no trace absorption in the 2-3 mm region where glasses tend to be highly absorbent due to the strong H2O band.

Sapphire has traditionally been the choice for such applications; however, it is difficult to polish. Sapphire is also slightly birefringent.The mechanical and chemical stability of YAG is similar to Sapphire, but YAG is not birefringent and is available with high optical homogeneity.

Benefits of this Technology

Excellent Thermal and Opto-Mechanical Properties

High thermal conductivity, 10 times better than glasses

Extremely hard and durable

Non-birefringent

This Technology is Available for Transfer
