Diffusion Bonding Crystal

Severe thermal lensing dictates the absolute power limit of conventional solid-state lasers. ATR Crystal engineers advanced composite laser rods through proprietary high-temperature diffusion bonding, seamlessly fusing active laser crystals with undoped end-caps. This flawless optical contact creates a monolithic structure designed specifically to extract devastating heat and sustain maximum power outputs without optical distortion.Ultimate Thermal Management: Effectively eliminates end-face deformation and dramatically decreases the thermal lensing effect for ultra-stable beam quality. Monolithic Integration: Achieved via precision optical contact methods and rigorous high-temperature bonding, resulting in a virtually invisible, flawless interface. High-Power Dominance: The critical architectural upgrade required to push continuous and pulsed laser systems to their absolute maximum power thresholds.

2 ) Improve beam quality

3 ) Decrease thermal effect

4 ) Improve efficiency

5 ) Compact size

Diffusion Bonding Process of Diffusion Bonding Laser Crystal

1 )Perfect optical contact between the crystals to be bonded;

2 ) Heating up of the two parts very slowly, to a very high temperature, probably 2/3 of the melt temperature or more, and exerting pressure to press the two parts together;

3 ) Keeping the bonded crystals for a certain period of time at this high temperature, so that diffusion takes place;

4 ) Slowly cooling the crystals (24 hours) down to room temperature.
