We demonstrate the generation of 68 fs secant hyperbolic pulses at a 105 MHz repetition rate with an average power of 520 mW from a diode-pumped Yb(3+):CaGdAlO(4) mode-locked laser. A semiconductor… (More)
We report an in situ thermal study of Yb-doped fluorite crystals Yb:CaF(2) and Yb:SrF(2) under high power pumping, with or without laser operation. The experiment combines simultaneously thermography… (More)
We demonstrate the generation of 99 fs pulses by a mode-locked laser oscillator built around a Yb:CaF(2) crystal. An average power of 380 mW for a 13 nm bandwidth spectrum centered at 1053 nm is… (More)
We report on an extended-cavity mode-locked laser based on an Yb:CALGO crystal operating either at 27 MHz and 93 fs pulse duration or at 15 MHz and 170 fs duration single-pulse regime. To the best of… (More)
Femtosecond mode-locked operation is demonstrated for the first time, to our knowledge, with a Yb:SrF(2) crystal. The shortest pulse duration is 143 fs for an average power of 450 mW. The highest… (More)
Yb:CaGdAlO4  has been recently demonstrated to be very interesting for the development of next generation diode–pumped short-pulsed modelocked lasers. In fact, this crystal demonstrated two very… (More)
We report the first femtosecond laser operation of Yb<sup>3+</sup>:CaGdAlO<sub>4</sub> crystal. Pulses as short as 47-fs have been obtained.
We report on long-cavity modelocked laser with Yb:CALGO crystal, with, first, a 27-MHz, sub 100-fs single-pulse regime and, second, a very atypical double-pulse dualwavelength femtosecond regime.
Since the demonstration, in 2004, of the first diode-pumped laser operation of Yb-doped calcium fluoride (CaF2 aka fluorite or fluorospar), an intense interest of the laser community has been… (More)
Yb3+:CaGdAIO4 is directly pumped with a 15 W 100 mum core fiber-coupled laser diode (LIMO) emitting around 980 nm. Two Gires-Tournois interferometers, each providing a negative group-velocity… (More)
