Stimulated Raman scattering presents one of important trends in nonlinear optics enabling to generate Stokes-shifted radiation at frequencies that are not readily available from solid state lasers. This method is suitable also because the phase matching fulfilment isn't required. To get stable and efficient Raman generation of picosecond and even femtosecond ultra-short Stokes pulses, the method of...
Diamond Raman lasers (DRLs) have been the subject of extensive research in the recent years. Continuous-wave and pulsed, intra-and extra-cavity DRLs emitting from UV to IR have been demonstrated [1]. The majority of these studies were carried out in the steady-state mode, when the pump pulse duration is longer than the dephasing time in diamond. Less work has been done on the transient mode, when...
Femtosecond mid-IR laser sources are of great demand due to its usefulness in a number of applications ranging from strong field phenomena to medical and environmental sensing. Nowadays devices based on OPA and OPCPA techniques had become a typical approach to produce mid-IR radiation. However, with Ti:Sapphire pump laser efficiency of OPAs in 4–5 μm range is rather low mainly due to the lack of suitable...
High-brightness continuous-wave (cw) beams at various wavelengths in the near and mid-infrared, visible, and ultraviolet are in demand for numerous applications spanning defence, astronomy, space-science, medicine and remote-sensing. While fiber lasers are an attractive solid-state technology for high-brightness cw beams, their output wavelengths are restricted to 1–1.1 μm (for ytterbium), 2 μm (thulium)...
