High-quality low-loss coatings for diode-pumped solid state lasers

The appearance of new types of lasers (for example, diode- pumped solid-state lasers) required development of the high quality low loss coatings for various spectral regions. These coatings can be divided into following groups: antireflective, high-reflective and cut-off filters. Various aspects of producing these coatings have been investigated. There are choice of the optimum construction of the optical coatings to obtain the required parameters in the specific spectral region, development of the production process to obtain the reproducing results when assembling lasers, study of optical parameters. All types of the optical coatings have been tested in the assembly of the lasers. Now these coatings are successfully used in the commercial lasers.
