Accumulated photon echoes were used to measure 1–800 ps dephasing times ( T 2 ) for the 4 I 9/2 → 4 G 5/2 , 2 G 7/2 transition of Nd 3+ ions located in two different symmetry sites in highly disordered CaF 2 -YF 3 crystals. The temperature depend

We study the narrow-band tunable Stokes radiation of frequency V s = 2 V 2 − V 1 generated by four-photon mixing in single-mode silica fibers under biharmonic tunable pulsed laser pumping with V 1 and V 2 ( < V 1) frequencies. The Stokes radiation

It is well known that Neodymium glasses are widely used as active media in powerful picosecond laser systems. However, low thermal conductivity of glasses with broad bands of absorption and luminescence limits their use in pulsed lasers with high rep
