50-fs pulse generation from a self-starting cw passively mode-locked Cr:LiSrAlF6 laser.
Femtosecond laser physics has been transformed by the advent of the titanium-doped sapphire laser, which has been mode locked by conventional and novel means (e.g., Refs. 1-7) and directly yielded pulses as short as 25 fs.' The observation of selfmode locking5 has led to the realization that the nonlinear refractive index of the laser medium can be used to provide both amplitude modulation, thr...
متن کاملPassively mode-locked cw Coumarin 6 ring dye laser.
The passive mode locking of a cw Coumarin 6 dye laser in a colliding-pulse ring configuration is reported. Pulses of less than 500-fsec duration have been obtained from 518 to 554 nm, with the shortest pulses obtained being of 96-fsec duration.
متن کاملStarting dynamics of a cw passively mode-locked picosecond Ti:sapphire/DDI laser.
We show that, for a cw passively mode-locked picosecond Ti:sapphire/DDI laser, the first autocorrelation trace with negligible cw background occurs at a delay time of 20 mu;s, or 1600 round trips from the first relaxationoscillation peak. The trace suggests that the pulse consists of a primary pulse as short as 4.4 ps and of small secondary pulses that form a much wider pedestal of the trace, e...
متن کاملSpatio-temporal intensity dynamics of passively mode-locked fiber laser
We present recent results on measurements of intensity spatio-temporal dynamics in passively mode-locked fibre laser. We experimentally uncover distinct, dynamic and stable spatio-temporal generation regimes of various stochasticity and periodicity properties in though-to-be unstable laser. We present a method to distinguish various types of generated coherent structures, including rogue and sh...
متن کامل1.21 W passively mode-locked Tm:LuAG laser.
A watt-level output passively mode-locked Tm:LuAG bulk laser with an InGaAs semiconductor saturable absorber mirror (SESAM) is demonstrated for the first time. A maximum average output power of 1.21 W at 2022.9 nm has been achieved with a pulse duration of 38 ps and a repetition rate of 129.2 MHz. The results indicate the potential of Tm:LuAG crystals as candidate for realizing high power ultra...
