Monolithic KTP （OPO用途）
Some applications of OPO require compact size and vibrationless operation, which may be achieved by using a monolithic design of the OPO element. External (cavity) mirrors are eliminated in this design, and the mirrors are evaporated onto the KTP crystal input and output faces directly. In addition, a higher frequency conversion efficiency can be achieved (see a figure on next page).
Elements with flat mirrors are a standard product. A curved mirrors design is under development and it is aimed to achieve a narrower divergence angle of the monolithic OPO element.
