Yb:YAG+Diamond
Our Yb:YAG+Diamond bonded crystal is formed by bonding Diamond to one end of Yb:YAG, improving overall Yb:YAG laser performance. Yb:YAG has a thermal-conduction coefficient of 0.14 W/cm/°K@25°C, while Diamond has a thermal conductivity of 1.465W/m/k (@100℃). Bonding them into Yb:YAG+Diamond reduces thermal effects and pump-induced thermal lensing and offers high slope efficiency, improved power, enhanced coherence and frequency-conversion capability. Crylink uses surface-activated bonding, a low-temperature or room-temperature technique characterized by surface cleaning and activation. Before bonding, bombarding the bonding surfaces with fast atoms or ion beams increases bond strength, enabling high-quality bonding among inorganic materials, metals and semiconductors. Compared with high-temperature thermal bonding, surface-activated bonding provides stronger interfacial bonding and better control of optical absorption loss and surface-figure changes. Thermal diffusion bonding leaves surface impurities trapped at the interface. Surface-activated bonding removes polishing residues, organic contamination and surface oxides, breaks chemical bonds and increases activation energy. The resulting Yb:YAG+Diamond crystals have high bond strength, low interfacial absorption loss, generally below 20ppm, and small surface-figure changes after bonding (<lamda/8). They are available as rods, slabs, waveguides or sandwich structures. Various end coatings can be provided, including AR/AR@1030nm on both faces. Yb:YAG+Diamond bonded crystals are widely used in holography, interferometry and optical storage, and in efficient, high-power diode-pumped solid-state lasers.

Atomic Density [Nd1.0%]: 1.26x1020 atoms/cm3 (Nd1.0%) Crystal Structure: Zircon Tetragonal, space group D4h-I4/amd a=b=7.1193A,c=6.2892A Density: 4.22g/cm3
Nd:YVO4 is one of the most promising commercially available diode pumped solid state laser materials. It has high laser induced damage threshold and good mechanical in addition to optical properties. Its large stimulated emission cross-section and high absorption of pump laser make it a right crystal for pocket laser. Nd: YVO4 can produce IR green and blue laser by using minor different set-up. A broad absorption band centered at 808nm and favorable mechanical properties make Nd:YVO4 well suited for compact, efficient, high power diode-pumped lasers. Natural birefringence gives rise to a highly polarized output at 1064.3 and 1342nm.
