Most optical materials are amorphous such as optical glass; however, there are a wide variety of crystals with some unique properties that are useful for optical and semiconductor applications. Some of them have a very good transmission from the ultraviolet to near IR regions. Their optical applications range from solid state laser generation, polarized beam generation, beam walk-off, phase modulation to new wavelength generation.

Optical crystals vary in material properties but all have a common foundation: they are grown from high-purity raw materials. These types of optical materials have excellent performance with lasers, semiconductor, medical, and military applications.

Sapphire, for instance, is highly durable and is commonly used in military application from the visible to the mid-wave infrared whereas BBO is very good for tunable laser sources, such as ultrafast Ti:Sapphire or dye lasers. These materials are manufactured using an assortment of methods that are specific to Photonchina.
