Laser diodes and diode-pumped solid-state laser systems: advantages, limits and application fields

摘要

A general comparative introduction on laser diodes and diode-pumped solid-state laser systems is presented. The main advantages and limits of these devices are reported. Low-to-medium power systems are mainly discussed in this report. With reference to the work carried out in our laboratory, we review on laser action of crystals at wavelengths different from their main laser transitions.In particular, red light generation through intra-cavity second harmonic generation processes is discussed, and the related problems of efficiency, beam quality and thermal effects are pointed out. Finally, as an example of system with great applicative perspectives both in scientific and technological fields, all-solid-state ultrashort pulse laser systems via passive mode-locking techniques are reviewed. The example of their application to the field of nonlinear microscopy is presented in some detail.
