چکیده

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 saturable absorber allows passive mode locking, and a 15 W diode laser is used to pump directly the crystal. To our knowledge this represents the highest average power ever obtained for a sub-100 fs diode-pumped Yb-bulk laser.

Diode-pumped continuous-wave and femtosecond laser operations of a heterocomposite crystal Yb:SrY4„SiO4...3O ̧Y2Al5O12

We report cw and femtosecond laser operations under diode pumping of a diffusion-bonding heterocomposite Yb-doped crystal: Yb:SrY4sSiO4d3O iY2Al5O12sYAGiSYS:Ybd. To show the advantages of this heterocomposite crystal over classical Yb:SYS crystal, we first investigate the high-power cw regime. A cw power of 4.3 W is demonstrated. The femtosecond regime is also investigated, and 1-W-average-powe...

Femtosecond Cr:Colquiriite Lasers Pumped by a Single Tapered Diode Laser

Ti:Sapphire lasers could provide tunable femtosecond pulses in the 680-1180 nm region; however, due to the requirement of expensive green pump sources, its current cost sets a barrier to its widespread adoption. As an alternative, Cr :Colquiriites (Cr:LiCAF, Cr:LiSAF, Cr:LiSGaF) also possess broad gain bandwidths and their total cw tuning range cover the 720-1110 nm region. Moreover, their broa...

Continuous - wave operation at 2 . 1 , um of a diode - laser - pumped , Tm - sensitized Ho : Y 3 AI 50 12 laser at 300 K

The 2.1-/im 5I7-518 laser transition in Ho3+ is attractive because of its long upper laser level lifetime, of the order of 5 msec, and its eye-safe wavelength. However, this laser typically is cooled to liquid-N2 temperatures to achieve continuous-wave (cw) or high-repetition-rate operation because its lower laser level is in the ground-state manifold, a few hundred inverse centimeters above th...

Continuous-wave laser operation of disordered double tungstate and molybdate crystals doped with ytterbium

Several ytterbium doped disordered doubles tungstate and molybdate crystals, NaGd(WO4)2, NaLa(WO4)2, NaLa(MoO4)2 and LiGd(MoO4)2, were grown with sufficient Yb-doping and optical quality. The crystal field splitting of the Yb 3+ multiplets and the lifetimes are similar to the biaxial monoclinic double tungstates but the peak absorption cross sections are roughly one order of magnitude lower. Ro...

Diode-Pumped Nd:YAG Green Laser with Q-Switch and Mode Locking

Gaining of a high peak power in the visible light range from a solid state laser with continuous diode pumping is a challenging task in several applications (high-precision material processing, nonlinear optics and Raman-spectroscopy, medicine, etc.). The technique of modulating the Q-factor of laser cavity (Q-switch) enables growth of the peak power approximately as ┬sp / ┬ph (here ┬sp is the ...
