180 W Single-Mode Laser Operation of an Yb:YAG Thin Disk using a Robust Direct-Bonding Process

Loïc Deyra Antoine Courjaud R. Bello M. J. Milla Johan Boullet

Summary form only given. Over the last few years thin disks lasers have shown breakthrough records in both average power and peak power [1,2]. The optimization of the bonding process for mounting the laser disk to the base heat sink is key to achieving these impressive levels of performance. Processes using UV-adhesive bonding on diamond [1] or soldering [3] have regularly been reported. Direct-bonding is a promising solution to further improve the thermal contact between the disk and the substrate [3,4], but to the best of our knowledge this process has not been applied to thin disk lasers for high power, single mode operation. In this work, we characterize an Yb:YAG thin disk bonded on silicon carbide (SiC) using an adhesive-free, direct-bonding process developed by Crystalline Mirror Solutions (CMS). We employ this thin disk in a laser cavity to obtain 178 W of CW output power in a single TEM ₀₀ mode beam.

High-power picosecond pulses by SPM-induced spectral compression in a fiber amplifier

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2005)

Thomas Schreiber A. Liem F. Roeser H. Zellmer Andreas Tuennermann

The fiber based generation of nearly transform-limited 10-ps pulses with 200 kW peak power (97 W average power) based on SPM-induced spectral compression is reported. Efficient second harmonic generation applying this source is also discussed.

Fiber coupling of an infrared femtosecond laser to a multiphoton microscope

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2007)

Antoine Courjaud Eric Mottay P. Legros Daniel Choquet

We report on a new fiber delivery system for coupling a compact, turn-key infrared femtosecond laser into a multiphoton microscope. Using a hollow core photonics crystal fiber with minimized dispersion, we achieve beam propagation on distances up to 4 meters. We measured a pulse duration close to 300 fs at the output of the microscope, for a femtosecond laser pulse duration of 200 fs. We present experimental parameters and system optimisation, and compare images obtained with fiber coupling versus direct coupling of the femtosecond laser.

On Yb:CaF2 and Yb:SrF2 : Review of spectroscopic and thermal properties and their impact on femtosecond and high power laser performance

HAL (Le Centre pour la Communication Scientifique Directe) (2011)

Frédéric Druon Sandrine Ricaud Dimitris N. Papadopoulos Alain Pellegrina Patrice Camy

We present an overview of laser results we obtained with Yb-doped calcium fluoride and its isotype strontium fluoride. In order to study the laser performance in femtosecond and high power regimes, spectral and thermal properties are first discussed including the potential of these crystals at room and cryogenic temperatures. Experimental demonstrations of high-power and ultrashort pulse oscillators and amplifiers are presented and analyzed.
