Abstract

Neodymium based monolithic lasers are known to be efficient, in particular when they include intracavity frequency doubling (ref 1). They can provide emission with highly stable frequency (ref 2). Finally, since optical degradation is more likely to occur at crystal interfaces, reliability is expected to be improved by monolithic designs. The advent of high power blue diode lasers has allowed to pump other rare earths, such as Praseodymium, emitting directly in the visible range and potentially emitting in the UV range with appropriate intracavity frequency doubling stage. In order to optimize the performances of these new lasers, it is interesting to develop monolithic designs of the lasers.
