Current Situation and Developing Trend of Optical Thin Films for DPSSL

摘要

A series of optical thin films for LD pumped all-solid-state laser are discussed. Because of the difference between the pumped wavelength and the output wavelength, various kinds of pumping ways, resonator structures and laser crystals, there are so many new kinds of optical thin films, including novel edge filters ,high reflection and antireflection coatings. The key problems in designing and coating are analyzed, and the researches carried out worldwide in this field are also given.
