0.59J/g•cm-3@0-20℃. Laser wavelength: 2.080μm. Molecular formula: Cr,Tm,Ho:Y3Al5O12. Orientation: <111>. Extinction ratio: >28dB. Flatness: λ/10@ 633 nm. Parallelism: <10arc seconds. Perpendicularity: <5arc minutes. Surface quality: 10/5. CTH:YAG, fully named Cr,Tm,Ho:YAG crystal, has a laser emission wavelength of 2080 nm and high pumping efficiency. It can be pumped by a flashlamp or laser diode. Cr,Tm,Ho:YAG crystals are widely used in laser medicine, measurement, and military applications. CTH:YAG also has good optical quality, low scattering loss, and high efficiency. Lasers made from Cr,Tm,Ho:YAG crystals are already widely used in laser medicine.
