THE TUNABLE VIBRONIC LASER MATERIALS BASED ON TRANSITION METAL IONS : SEARCH OF NEW SYSTEMS AND EXCITED STATE SPECTROSCOPY

For they are stable and they allow to get intense and tunable radiations in a large spectral domain, the vibronic solid state laser materials based on transition metal ions such as Ti3+, Cr3+, V2+, Ni2+ and Co2+ give rise presently to a renewed and increased interest, and more particularly in our laboratory as concerns the optical studies
