~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 *4 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 (*4 hours or even more) down
to room temperature.
Diffusion Bonded Crystals (DBC) are crystals consisting of two, three or more parts with different doping levels or different dopant, usually one laser crystal and one or two undoped crystals combined by optical contact and further bonded under high temperature.
Lasertec Inc is a leading manufacturer of finished composite crystal and glass components for solid-state lasers in China. We hold special diffucsion bonding technology, which enables the joining of crystal materials without the use of an adhesive or an organic or inorganic bonding aid. This innovative technology reduces thermal lens effect of laser crystals, provides integral components to make compact lasers.
Our diffusion bonding crystals mudles allows for the separation of functionalities of laser components into lasing and non-lasing regions, which is critical for high power DPSSL systems. Our componets offer a new degree of freedom for the design engineer\'s realization of rugged, compact, solid state laser systems.
We are support below standard diffusion bonding cyrstals :
1. Vanadate diffusion bonding crystals modules
Based diffusion bonding technology YVO4 or GdVO4 components
are extremely useful for higher power in YVO*-based laser systems.
Undoped end-caps increase damage threshold by separating the pump
input face with the lasing doped portion.
2.Garnet diffusion bonding crystals
Based diffusion bonding technology microchips, especially in
the form of Nd:YAG/Cr4+:YAG passively q-switched microchips have
found a host of applications due to their compact size and the
incorporation of both the lasing material and q-switch into a
monolithic element. This approach minimizes system complexity and
system size, and maximizes efficiency.
3. KTP and KTA diffusion bonding crystals
Lasertec offers the walk-off correction of non-linear crystals such as KTP through our bonding process. We possess the criteria to design walk-off corrected composites employing uniaxial and biaxial crystals.We can manufacture walk-off corrected composites according to customer specifications and are able to assist with the complete design of components or devices.
