Satellite-based laser-based remote sensing (lidar) of the atmosphere can be used for meteorology, atmospheric chemistry and climate change but requires high energy (100mJ-class) lasers with precision wavelength control. A high energy Alexandrite laser source is an interesting alternative to Nd:YAG in future Earth Observation missions with its added scientific benefit of broad wavelength tunability...
Femtosecond 1 μm lasers are widely used in numerous scientific and industrial applications [1, 2]. Such oscillators are intensively developed and ultrafast sub-100 fs operation has been already demonstrated in several ytterbium-doped active media. One of the most interesting among them and relatively shortly investigated is Yb:CaF2. This is a simple cubic crystal, with very broadband emission spectrum...
