Ultrafast Yb:CALGO laser with low repetition rate
Main Author: Arkady Major Organization: University of Manitoba, Canada Femtosecond diode-pumped Kerr-lens mode-locked Yb:CALGO laser operating at ~10 MHz of repetition rate was demonstrated. The laser produced 66 fs pulses directly from the oscillator with 650 mW of average output power. This corresponds to the pulse energy of 64 nJ with a peak power of 0.97 MW. No external pulse compression was used. |

High-brightness 14.1 kW incoherent beam combining of fiber lasers based on an all-fiber 7×1 signal combiner
Main Author: Zilun Chen Organization: National university of defense and technology, China We demonstrate an all-fiber 7×1 signal combiner with an output core diameter of 50 μm for high power incoherent beam combining of seven home-made Yb-doped single-mode fiber lasers around wavelength of 1080 nm and output power of 2 kW. 14.1 kW combined output power is achieved with a total transmission efficiency of higher than 98.5% and a beam quality of M2=5.37. To the best of our knowledge, this is the highest output power ever reported for all-fiber structure beam combining generation, which indicates the feasibility and potential of 10 kW high brightness incoherent beam combining based on an all-fiber signal combiner. |

A Compact Watt-level Sub-picosecond Fiber-coupled Dual-wavelength CPA Laser System
Main Author: Xinyang Su Organization: Universiy of Waterloo, Canada A compact, two-color fiber-coupled chirped pulse amplification laser system is described. The system delivers synchronized sub-picosecond pulses with average power of 1.9 W and 0.4 W at wavelengths 1025 nm and 1085 nm, respectively. |

Single-pass pulse compression from 170 fs to 5.1 fs
Main Author: Young-Gyun Jeong Organization: INRS-EMT, Canada We present an extreme pulse compression from 50 cycles down to the single-cycle regime employing a 6-m-long hollow-core fiber. 1 mJ, 170 fs pulses from an Yb laser are compressed down to 5.1 fs, which is 1.5 optical cycles at 1030 nm. |

Utlrafast thin-disk oscillators at 1 µm and 2 µm wavelengths
Main Author: Oleg Pronin Organization: Max-Planck-Institut für Quantenoptik, Germany The combination of Kerr-lens mode-locking (KLM) and thin-disk technology has enabled tremendous progress in the development of 1 μm femtosecond Yb:YAG thin-disk oscillators, with their direct output reaching nearly 300 W of average power and 60 MW of peak power. Recently, this technology has been transferred to the longer 2 μm wavelength, resulting in a new femtosecond Ho:YAG thin-disk platform. This new Ho:YAG oscillator readily provides an average power up to 25 W—the highest average power of any mode-locked oscillator in the 2 μm region. The state of the art in both 1 μm and 2 μm oscillator technologies, and the future directions towards the generation of even higher average and peak powers, will be discussed and presented. Ultra-broadband infrared generation will also be addressed. |
