Presentations

MTW-OPAL - a Technology Development Platform for Ultra-Intense All-OPCPA Systems (STh4N.1)
Presenter: Jake Bromage, University of Rochester

Activation results will be presented for MTW-OPAL, a new all-OPCPA laser using technologies suitable for kilojoule-femtosecond systems, highlighting 140-nm-wide amplification in DKDP to >10 J with 30% efficiency and subsequent recompression to 20 fs.

1 MHz, few-Cycle, CEP Stable OPCPA With Dual Channel Output at 800 nm and 2 µm Wavelength (STh4N.2)
Presenter: Jan Buss, Class 5 Photonics GmbH

A high repetition rate, optical parametric chirped-pulse amplifier (OPCPA) with dual output at 800 nm and 2 µm is presented. White light seeded, CEP stabilized pulses with 9.1 fs are achieved on less than a square-meter footprint

  Paper

Generation and Amplification of High Power Ultrafast mid-Infrared Pulses Through ZGP (STh4N.3)
Presenter: Fangjie Zhou, University of Central Florida

We present the generation of femtosecond pulses centered at 3 and 8 μm through a ZnGeP2-based Optical Parametric Chirped Pulse Amplifier. The output can be used for a two-color high harmonic generation scheme

  Paper

Robust Self-Referenced Generator of Programmable Multi-Millijoule THz-Rate Bursts (STh4N.4)
Presenter: Vinzenz Stummer, TU Wien

We demonstrate a technique for the programmable generation and multi-millijoule amplification of ultrashort pulse bursts, which can be applied to any master-oscillator regenerative-amplifier system with very low implementation complexity and high stability in burst performance.

  Paper

High-Peak Power Polarization-Multiplexed Yb:CaF2 Dual-Comb Solid-State Laser With 100-fs Pulse Duration (STh4N.5)
Presenter: Justinas Pupeikis, ETH Zurich

We demonstrate a diode-pumped Yb:CaF2 dual-comb oscillator at 80-MHz repetition rate. The common-path polarization-multiplexed cavity delivers >2.1 W of output power in each comb with 100-fs pulse duration exceeding 230-kW peak power.

  Paper

Nonlinear Fiber Amplifier for Intensity-Noise Reduction to the Shot-Noise Limit (STh4N.6)
Presenter: Marvin Edelmann, Center for Free-Electron Laser Science

We demonstrate an all-PM fiber amplifier for intensity-noise reduction of pulsed input signals. Based on the nonlinear phase difference accumulation of copropagating orthogonal polarization modes in a PM-fiber, shot-noise limited noise reduction is verified.

  Paper

Generation of 95 fs mid-IR Pulses With 1.8 W Average Power Using an Er: ZrF4 Fiber Mode-Locked Oscillator and a Nonlinear Amplifier (STh4N.7)
Presenter: Yifan Cui, University of Michigan

Ultrashort mid-IR pulse train with 95 fs pulse width, 37.4 nJ pulse energy and 1.8 W average power was generated at ~2.85 µm from a simple Er:ZrF4 fiber nonlinear amplifier seeded by a mode-locked oscillator.
