Yb: YAG+Diamond bonding crystal is a bonding crystal formed by bonding diamond at one end of Yb: YAG, which can effectively improve the comprehensive performance of Yb: YAG laser.

The thermal conductivity of Yb: YAG is 0.14 w/cm/ ° k@ 25 °C, and the thermal conductivity of diamond crystal is 1.465w/m/k (@ 100 ℃). Yb: YAG+Diamond bonded crystal is formed by bonding at both ends, which can effectively improve the thermal effect of Yb: YAG crystal, reduce the thermal lens effect formed during laser pumping, have high slope efficiency, and improve excellent power, enhanced coherence and frequency conversion ability.

CRYLINK uses surface activation bonding technology, which is a bonding technology at low or normal temperatures. The typical features are surface cleaning and surface activation. Before bonding, the bombardment of fast atoms or ion beams on the bonding surface can effectively increase the bonding strength and achieve high-quality bonding between inorganic materials, metals, and semiconductor materials.

Compared with the high-temperature thermal bonding method, the surface activation bonding technology has a higher bonding force interface, better optical absorption loss, and surface shape change control. In contrast, the impurities on the thermal diffusion bonding surface cannot be removed and are bonded on the bonding surface. Surface-activated bonding technology has the advantages of removing various polishing residual components, removing organic pollutants, removing surface oxide layers, breaking chemical bonds of materials, and improving activation energy.

The Yb: YAG+Diamond bonding crystal produced has high bonding strength, small bonding surface absorption loss (generally less than 20ppm), and small change of bonding surface shape (bonding surface shape <lamda/8). The shape of the bonded crystal can be a rod, plate, waveguide, or sandwich. Various types of coatings can be provided at both ends of the bonded crystal, such as two-end antireflection films ar/ AR@1030 nm Etc. Yb: YAG+Diamond bonded crystals are widely used in holography, interference, optical storage, and other fields. They can also be used in high-efficiency and high-power diode-pumped solid-state lasers.
