Direct growth bonded Tm:YAP laser crystal

Tm:YAP crystals are suitable for commercial laser diode (LD) pumping, possessing numerous advantages such as direct output of linearly polarized laser, high conversion efficiency, high thermal conductivity, good mechanical and chemical stability, making it an important laser crystal in the 2-micron band. However, Tm:YAP crystals belong to the orthorhombic system and are biaxial crystals with significant anisotropy in thermal expansion coefficient. Traditional thermal diffusion bonding technology produces Tm:YAP composite crystals with low bonding strength. The undoped YAP crystal and Tm:YAP crystal at the end face composite, due to crystallographic differences, will cause additional polarization loss. After years of technological research and development, Leisheng Company has adopted proprietary patented technology to achieve the direct growth of 40mm diameter large-size YAP/Tm:YAP/YAP composite crystal blanks, successfully solving the problems of composite blank melting cracking and composite interface scattering defects, and can stably provide users with various sizes and specifications of customized high-quality directly grown Tm:YAP bonded crystals.

Product Description

Tm:YAP crystals are suitable for commercial laser diode (LD) pumping, possessing numerous advantages such as direct output of linearly polarized laser, high conversion efficiency, high thermal conductivity, good mechanical and chemical stability. It is an important laser crystal in the 2-micron wavelength band. However, Tm:YAP crystals belong to the orthorhombic system and are biaxial crystals with significantly anisotropic thermal expansion coefficients. Traditional thermal diffusion bonding technology produces Tm:YAP composite crystals with low bonding strength. The undoped YAP crystal and Tm:YAP crystal at the end face, due to crystallographic orientation differences, cause additional polarization loss. After years of technological breakthroughs, Leisheng Company, using its proprietary patented technology, has achieved the direct growth of 40mm diameter large-size YAP/Tm:YAP/YAP composite blanks, successfully solving the problems of composite blank melting cracking and composite interface scattering defects. We can stably provide users with customized high-quality directly grown Tm:YAP bonded crystals of various sizes and specifications.
