Efficient YLF|Pr:YLF Composite Microlaser at 639 nm
Currently, Praseodymium (Pr<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3+</sup>) doped fluoride crystals (LiYF4) and glasses (ZBLAN) are recognized for the development of multi-colour laser sources directly emitting visible radiation under pumping by blue GaN-based laser diodes or semiconductor lasers [1], [2]. Monolithic cavities employing composite gain media (i.e., those consisting of an undoped and a rare-earth doped part) benefit from reduced intracavity losses and improved thermal management. Such monolithic micro-lasers emitting in the visible are relevant for applications in biology, e.g., super-resolution microscopy, or as seed sources for laser amplifiers. We report on an efficient and power scalable diode-pumped monolithic red laser employing a composite gain medium based on Pr<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3+</sup>-doped LiYF4 (Pr:YLF) crystal.
