چکیده
Continuous-wave mode-locked femtosecond 2-m solid-state laser with a c-cut Tm:CaYAlO4 (6 at.%) as gain medium was experimentally demonstrated. The mode locked laser generated stable pulses with average output power as high as 531 mW, pulse duration of 496 fs, and repetition rate of 97 MHz at 1975 nm. The research results show that Tm:CaYAlO4 is an excellent gain medium for femtosecond pulse generation at 2 m wavelength.

Diode-pumped mode-locked femtosecond Tm:CLNGG disordered crystal laser.
A diode-end-pumped passively mode-locked femtosecond Tm-doped calcium lithium niobium gallium garnet (Tm:CLNGG) disordered crystal laser was demonstrated for the first time to our knowledge. With a 790 nm laser diode pumping, stable CW mode-locking operation was obtained by using a semiconductor saturable absorber mirror. The disordered crystal laser generated mode-locked pulses as short as 479...

We describe a diode-pumped Kerr-lens mode-locked Cr(3+):LiSrAlF(6) laser that produces 50 mW of 70-fs pulses in the 820-890-nm range when pumped by two red diodes of 400 mW each. By using a lower-transmission output coupler we have demonstrated for the first time to our knowledge a self-starting regime with an output power of 10 mW and 55-fs pulses.

We demonstrate a 1.2-GHz repetition rate, diode-pumped, self-starting, 168-fs (FWHM) pulsewidth Yb:KYW laser mode-locked by a carbon nanotube (CNT) saturable absorber mirror. To our knowledge, this result corresponds to the highest repetition rate from CNT-mode-locked femtosecond bulk solid-state lasers, reaching the GHz regime for the first time.

A diode-pumped passively mode-locked Yb:Lu2Si2O7 (Yb:LPS) laser is demonstrated for the first time, to our knowledge. Using a commercial semiconductor saturable absorber mirror (SESAM) as the mode locker and a pair of GiresTournois interferometer (GTI) mirrors for group-velocity dispersion (GVD) compensating, we have obtained stable femtosecond mode locked pulses. Two output couplers of transmi...

A stable diode pumped Kerr-lens mode-locked (KLM) Yb:LuYSiO5 (Yb:LYSO) laser of generating 61 fs pulses at a central wavelength of 1055.4 nm is experimentally demonstrated. This is, to the best of our knowledge, the first demonstration of femtosecond KLM operation in Yb:LYSO laser, and it is believed that 61 fs is the shortest pulse duration ever produced from an Yb-doped orthosilicate laser.
