Diffusion Bonding Crystals(New Product)

Hot application for KTP diffusion bonding, please see Here

Diffusion bonding means that the two parts that are bonded together diffuse into one another and they become as one single crystal. The technology of diffusion bonding includes the following steps:
1. Perfect optical contact between the crystals to be bonded.
2. Heating up of the two parts very slowly (within 24 hours or even more), 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 certain period of time at this high temperature, so that diffusion takes place.
4. Slowly cooling the crystals (24 hours or even more) down to room temperature.

Advantage
These Diffusion Bonded composite crystals are used to effectively decrease heat effect of Solid-State High-Power Laser.

High damage threshold

Improve beam quality

Decrease thermal effect

Improve efficiency

Compact size

Composite laser rod is a crystal consisting of two, three or more parts with different dopant level. Usually, doped and undoped material used.
Dopant level and rod configuration can vary as well as the number of parts. It can have different wedged structure, Brewster angles, etc.
