Frontiers in Ultrafast Optics: Biomedical, Scientific, and Industrial Applications XXI.
We report on the first industrial UV femtosecond laser with more than 100W average output power. The laser is ideally suited for high throughput precision applications, in particular for glass and polymer cutting in display industry. Thanks to its fl

Absolute timing jitter from a mode-locked laser is characterized with a record low noise floor of 122 y s / H z ( 1.5 × 10 − 14 s 2 / H z ). We develop a novel measurement technique using cross-spectrum methods in combination with a dual balanced

Residual timing noise from two synchronized diode pumped solid-state ytterbium-doped ultrafast laser oscillators is investigated. The lasers are passively mode-locked with a SESAM, which allows self-starting and stable laser operation coupled to a ro

A combination of cross-spectral analysis and balanced optical cross-correlation techniques is proposed to access the absolute timing jitter of one laser mode-locked solid-state laser. This method gives a record jitter detection floor.

We report a 4.1 mJ, 100 Hz, ∼1.7 ps DUV laser at 257.5 nm from a frequency-quadrupled Yb-YAG chirped-pulse amplifier. An infrared-to-DUV conversion efficiency of ∼20% is achieved with a good beam quality.

Recent advances on Ytterbium ultrafast lasers have led to compact and versatile systems with high average output power, potentially high pulse energy and easily tunable repetition rate. Such lasers are well suited for time-resolved pump-probe experim

We report on a diode pumped ultrafast amplifier based on Yb:CaF2 delivering 32 mJ, at a repetition rate of up to 200 Hz, with a central wavelength of 1030nm. The pulses have spectral bandwidth of 5.5 nm, supporting a theoretical pulse duration of 250
