Ultrafast disk lasers and amplifiers
SPIE Proceedings, 2012Disk lasers with multi-kW continuous wave (CW) output power are widely used in manufacturing, primarily for cutting and welding applications, notably in the automotive industry. The ytterbium disk technology combines high power (average and/or peak power), excellent beam quality, high efficiency, and high reliability with low investment and operating

Ultrafast laser-written dual-wavelength waveguide laser
Optics Letters, 2012We report the performance of a dual-wavelength waveguide laser based on a phase-modulated sampled-grating architecture fabricated using the femtosecond laser direct-write technique. The waveguide laser was written in Yb-doped phosphate glass and had a narrow linewidth (60 dB), 5 mW output power per channel, and wavelength separation of 10 nm.

Ultrafast Chaos from Semiconductor Lasers
Topical Meeting on Ultrafast Phenomena, 1986Ultrafast chaos of 100 ps time regime was observed from semiconductor lasers with delayed feedback. This is the fastest chaos ever observed directly to our knowledge.

Ultrafast Diode-Pumped Lisaf Lasers
Conference on Lasers and Electro-Optics Europe, 1996LiSAF crystals (LiSrAlF6 doped with Cr3+ ions) are very interesting amplifier materials due to a large fluorescence bandwidth in the near infrared (800 nm to 1 μm) and an absorption band in the red (600-700 nm). Commercial high power single-stripe laser diodes emitting in this wavelength band are available since a few years.

The Journal of the Acoustical Society of America, 1996
Acoustic waves generated by ultrashort optical pulses provide a novel approach to materials characterization. Frequencies in the gigahertz to terahertz regime, corresponding to acoustic wavelengths from sub-10 nm to ∼1 μm, can be used to investigate thin layers and nanostructures of commensurate dimensions.
