“…Approximately 80% of the pulse energy was contained in the compressed dominant pulse, leading to a peak power estimate of ϳ20 kW. This peak power result represents an order of magnitude improvement over previous all-fiber CPA systems, and the source described here can immediately supersede bulk solid-state lasers in applications such as nonlinear microscopy 13 and polymer ablation. 14 However, the fact that the chirp is not fully linearized in the DSF means that increased peak powers and improved pulse prof iles could be obtained by optimizing f iber parameters.…”

We demonstrate an ultrashort all-fiber-integrated chirped-pulse amplification system yielding 1-ps pulses with 20 kW of peak power. 40-ps initial pulses generated by an externally modulated laser diode are chirped by self-phase modulation in a conventional fiber, amplified, and compressed in 110 m of air-core photonic bandgap fiber. The compressed pulses are frequency doubled in a periodically poled KTP crystal with up to 48% efficiency and applied to supercontinuum generation in a holey fiber, resulting in a high-power uniform continuum that stretches from 430 to 1450 nm.

“…Laser sources at the shorter green and blue wavelengths provide clear advantages over infrared lasers in allowing for stronger beam focusing and enhanced resolution in multi-dimensional imaging techniques [1]. By using ultrashort-pulse lasers in preference to continuous-wave sources, it is possible to investigate ultrafast biological processes [2], increase the resolution of spectroscopy, microscopy [3,4], etc.…”

We have demonstrated an ultrashort, compact green light radiation by frequency doubling of an all-fiber ytterbium-doped fiber laser source in a PPKTP waveguide fabricated by femtosecond laser pulses. Using the fabricated PPKTP waveguide crystal containing a 10 mm single grating with a period of 9.0 μm, we generate 310 mW of picosecond radiation at 532 nm for a fundamental power of 1.6W, corresponding to a conversion efficiency of 19.3%. The temperature tuning range of 8°C is achieved for a fixed fundamental wavelength of 1064 nm, the FWHM of the wavelength tuning curve is 4.2 nm at room temperature. The generated ultrashort pulses at 532 nm are of great importance and have comprehensive applications in photobiology research and high-resolution spectroscopy.

“…Experimentally, thanks to the recent development of ultrafast spectroscopy techniques, it is now possible to monitor the femtosecond dynamics of an electron gas confined in metallic nanostructures such as thin films [1,2,3,4,5,6,7,8], nanotubes [9], metal clusters [10,11] and nanoparticles [6,7,12,13]. Therefore, meaningful comparisons between experimental measurements and numerical simulations based on microscopic theories are becoming possible.…”
