The Cutting Process of Ti:Sapphire Crystal
Ti:Sapphire crystal cutting processOrient the crystal→ Select crystal blank with high quality → Glue blank → Cut blank→ Brewster angle cut→ cleaning 1）Set M Direction：The unusable part (with more air bubbles and grain boundaries) at the top of the crystal blank along the M direction should be roughed and removed with a single-axis machine. During […]
The operating instructions for directional cutting of crystals
Crystals usually need to be cut along a certain crystal plane direction when cutting. In order to prepare to remove a certain crystal plane, we propose this technical solution for actual cutting applications, which can conveniently and accurately cut the required crystal plane. (1) First, perform preliminary orientation rough grinding on each crystal plane to […]
The Growth of YCOB Nonlinear Crystals
YCa4O(BO3)3 (YCOB) is a nonlinear crystal possessing good thermal, mechanical and nonlinear optical properties. It is regards the important candidate frequency conversion material for the high-average power laser system. Compared with other nonlinear crystals commonly utilized in OPCPA systems, YCOB crystal has several prominent properties: high damage threshold, moderate thermal conductivity, and nonlinear coupling.YCOB nonlinear plate was used in […]
The Growth and Testing of Yb:YAG Crystals (7.5%,3 inch)
Yb:YAG crystal has a melting point of 1970℃, which is a uniformly molten compound. It is usually grown by induction heating melt pulling method: First, the crystal raw material to be grown should be heated in a high temperature-resistant crucible until melted, and then adjust the temperature so that undercooling the upper part of the […]
