YVO4+Nd:YVO4+YVO4 Diffusion bonded DBC Laser Crystal consists of one laser crystal and one or two undoped material.
YVO4+Nd:YVO4+YVO4 Bonding ( Diffusion bonded ) Crystals are combined by optical contact method and further bonded under high temperature.
YVO4+Nd:YVO4+YVO4 Bonding ( Diffusion bonded ) Crystal helps to decrease thermal lens effect considerably.
Laser crystal integration using a neodymium-doped yttrium vanadate ( or orthovanadate ) laser crystal, and non-doped yttrium vanadate crystals that function as cold fingers has been demonstrated.
In our Bonding ( Diffusion bonded ) technique of YVO4+Nd:YVO4+YVO4 crystals, a newly developed dry etching process was adopted in the preparation for contact of mechanically polished surfaces.
In the successive heat treatment process, temperature optimization was essential to get rid of precipitation of vanadic acid caused by the thermo-chemical reaction in a vacuum furnace.
The surface of Bonding ( Diffusion bonded ) YVO4+Nd:YVO4+YVO4 Crystals of 5 mm 6 mm was studied via optical characteristics and magnified inspection.
In addition, we also compared the integrated Bonding ( Diffusion bonded ) YVO4+Nd:YVO4+YVO4 Crystals with a normal one in laser output power pumped by a CW Laser diode.
Coupletech can supply three kinds of Diffusion Bonded Crystals:
