YAG+Nd: YAG+YAG bonding crystal is a bonding crystal formed by bonding pure YAG at both ends of Nd: YAG, which can effectively improve the comprehensive performance of Nd: YAG laser.

The thermal conductivity of Nd: YAG is 14w/m/k, 20 º C, 10.5w/m/k, 100 º C, and the thermal conductivity of pure YAG crystal is 14w/m/ K@20 ℃、10.5W/m/ K@100 ℃, both ends are bonded to form YAG+Nd: YAG+YAG bonded crystal, which can effectively improve the thermal effect of Nd: YAG crystal, reduce the thermal lens effect formed during laser pumping, improve the beam quality of laser, improve the output efficiency of 1064 nm and 1319 nm laser, improve the stability of laser output capacity, and improve the service life of laser.

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 produced YAG+Nd: YAG+YAG bonding crystal 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 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@1064 nm, or S1: HR@1064 nm ，S2: PR@1064 nm Etc. YAG+Nd: YAG+YAG bonded crystals are widely used in biophysics, medicine, military, machinery, scientific research, architecture and other fields.
