CTH:YAG Crystals and Components

CTH:YAG -yttrium aluminium garnet laser crystals doped with chromium, thulium and holmium ions to provide lasing at 2.13 microns are finding more and more applications, especially in the medical industry. The inherent advantage of the crystal is that it employs YAG as the host. YAG's physical, thermal and optical properties are well known and understood by every laser designer.

Lasers operating at 2.13 microns couple well into water and body fluids, and can take advantage of using silica fibers for easy, accurate beam delivery. CTH:YAG can be readily Q-switched with either electro-optic material such as LiNbO3 or acousto-optics. Lasers using CTH:YAG are successfully used for medical procedures such as fragmentation of gallstones and for vascular welding.

Proprietary crystal preparation technology has been developed to overcome poor lasing efficiency, one of the major impediments to the use of laser materials in the 2 microns wavelength range. This technology allows production of CTH:YAG laser crystals with high optical quality, low scattering losses, and high efficiency. CTH:YAG laser crystals optimise the usefulness of the sensitiser ions for the holmium basing conditions at room temperature.

CTH:YAG laser crystals are offerred in sizes from 3 mm to 10 mm diameter, with lengths up to 150 mm long. Call upon our depth of experience in research, crystal growth and laser rod fabrication.
