Abstract

The expanding field of solid state lasers and devices forms an interesting challenge for the development of coatings. A wide variety of different specifications, often contradictory, has to be matched. The choice of deposition process and coating material ist crucial with respect to losses, damage threshold, optical specifications and their long term stability. Especially diode pumped solid state lasers include a number of new applications for optical coatings, which are discussed in this paper. Band-pass filters, beam dividers, two-wavelength coatings etc. on bulk materials like Nd:YAG, KTP etc. have been developed. Different design approaches are compared and practical aspects of coating deyelopments are discussed. Ion based processes lead to superior results in most of the cases, but conventional evaporative coating processes give adequate results sometimes. Advantages and disadvantages have to be discussed for every approach separately.
