TL;DR: A cw-pumping, repetitively Q-switched, InGaAs-diode-pumped Yb:YAG laser has been demonstrated at room temperature and no optical damage was observed despite the high saturation fluence and the short pulse length.
Abstract: A cw-pumped, repetitively Q-switched, InGaAs-diode-pumped Yb:YAG laser has been demonstrated at room temperature. An output energy of as much as 72 microJ/pulse at 1.03 microm with a pulse length as short as 11 ns (FWHM) was attained. No optical damage was observed despite the high saturation fluence (~10 J/cm(2)) of the Yb:YAG laser and the short pulse length.

TL;DR: This Yb:KGW laser has a high potential for stable frequency comb generation and could increase the pulse repetition rate up to 4 GHz with an average power of 900 mW and a pulse duration of 290 fs.
Abstract: 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 tapered diode laser is used as a pump source. Stable soliton modelocking is achieved with a semiconductor saturable absorber mirror (SESAM). The obtained average output power is 1.1 W and corresponds to a peak power of 3.9 kW and a pulse energy of 1.1 nJ. With harmonic modelocking we could increase the pulse repetition rate up to 4 GHz with an average power of 900 mW and a pulse duration of 290 fs. This Yb:KGW laser has a high potential for stable frequency comb generation.

TL;DR: In this article, a 40mJ ArF* laser with pulse duration ∼10 ps and spatial and spectral properties close to the transform limits is described, and substantial extraction of the available energy from the final amplifier is demonstrated, providing direct evidence against the presence of significant nonlinear losses in the amplifying medium up to an intensity of ∼1 GW/cm.
Abstract: A 40‐mJ ArF* laser with pulse duration ∼10 ps and spatial and spectral properties close to the transform limits is described. Substantial extraction of the available energy from the final amplifier is demonstrated, a fact providing direct evidence against the presence of significant nonlinear losses in the amplifying medium up to an intensity of ∼1 GW/cm.2

TL;DR: In this article, a combination of a passively mode-locked Nd:YVO 4 pump laser with 10 ps pump pulse duration at 1064 nm and a dispersion-adapted air-silica microstructured fiber generates supercontinuum radiation with an average power of 2.4 W in a spectral range from 700 to 1600 nm.
