Nonlinear propagation of intense femtosecond laser pulses in bulk transparent media leads
to a specific propagation regime, termed femtosecond filamentation, which in turn produces …

Ultrafast laser physics continues to advance at a rapid pace, driven primarily by the
development of more powerful and sophisticated diode-pumping sources, the development …

The nonlinear refractive index, n_2, of sapphire was experimentally measured in the 550–
1550-nm wavelength range by use of a picosecond Z-scan technique. It was found that in …

We report the first demonstration, to our knowledge, of soft-aperture Kerr-lens mode locking
in a diode-pumped femtosecond Yb^ 3+: YVO_4 laser. Near-transform-limited pulses as …

We report a highly efficient diode-pumped femtosecond Yb: KYW laser with a compact three-
element resonator. Near-transform-limited pulses of 107fs duration at a centre wavelength of …

We report on the first demonstration, to the best of our knowledge, of sub-100 fs pulses
directly from the diode-pumped mode-locked Yb: KGW bulk oscillators operated at a low …

A high-power (> 1 W) pure Kerr-lens mode-locked bulk Yb: KGW laser with multimode fiber-
coupled diode pumping was demonstrated. The laser delivered 240 fs pulses with 2.3 W of …

TION excited-state lifetime, tight pump and signal light confinement, and excellent pump-
mode overlap with the active region allows us to achieve extremely large excitation …

A high-power, diode-pumped, semiconductor saturable absorber mode-locked Yb (5%):
KGW bulk laser was demonstrated with high optical-to-optical efficiency. Average output …

We present a diode-pumped Yb: KGW laser with a repetition rate of 1 GHz and a pulse
duration of 281 fs at a wavelength of 1041 nm. A high brightness distributed Bragg reflector …
