In this article, a semiconductor saturable absorber mirror mode-locked thin disk laser based on Yb:Lu2O3 with an average power of 141W and an optical-to-optical efficiency of more than 40%.Abstract:
We present a semiconductor saturable absorber mirror mode-locked thin disk laser based on Yb:Lu2O3 with an average power of 141W and an optical-to-optical efficiency of more than 40%. The ideal soliton pulses have an FWHM duration of 738fs, an energy of 2.4μJ, and a corresponding peak power of 2.8MW. The repetition rate was 60MHz and the beam was close to the diffraction limit with a measured M2 below 1.2.read more

The physics of ultra-short laser interaction with solids at non-relativistic intensities
TL;DR: In this article, a review of laser-matter interactions is presented, with a broad range of intensities from those inducing subtle atomic excitations (∼1010 W/cm2) up to high intensity when solid is swiftly transformed into hot and dense plasma.

Semiconductor saturable absorber mirrors (SESAM's) for femtosecond to nanosecond pulse generation in solid-state lasers
Ursula Keller,K.J. Weingarten,Franz X. Kärtner,D. Kopf,B. Braun,I.D. Jung,R. Fluck,C. Honninger,Nicolai Matuschek,J. Aus der Au +9 more
TL;DR: In this paper, the design requirements of SESAM's for stable pulse generation in both the mode-locked and Q-switched regime were reviewed, and the combination of device structure and material parameters provided sufficient design freedom to choose key parameters such as recovery time, saturation intensity, and saturation fluence.

TL;DR: This Letter reports on the generation of 830 W compressed average power from a femtosecond fiber chirped pulse amplification (CPA) system and discusses further a scaling potential toward and beyond the kilowatt level by overcoming the current scaling limitations imposed by the transversal spatial hole burning.

Fifteen Years of Work on Thin-Disk Lasers: Results and Scaling Laws
A. Giesen,J. Speiser +1 more
TL;DR: In this paper, the scaling laws for thin-disk laser design have been investigated for continuous-wave (CW) and Q-switched operation as well as for amplification of short (nanosecond, femtosecond) pulses.

Stabilization of solitonlike pulses with a slow saturable absorber
Franz X. Kärtner,Ursula Keller +1 more
TL;DR: It is shown that a soliton of the nonlinear Schrödinger equation perturbed by filter losses and/or the finite gain bandwidth of amplifiers can be kept stable by saturable absorbers with a relaxation time much longer than the width of the soliton.
