this stand-alone and complete measuring station is to be operated with an already existing excitation laser system consisting of an ultrashort pulse
laser with regenerative amplifier (coherent legend elite, 6 j @ 4 m).
SPM-SSFS sources therefore provide a flexible platform for ultrashort pulse
generation, which results in a tunable output energy and SC width, without active optical elements such as optical modulators.
The solution is selecting a laser with an ultrashort pulse
length to minimize burrs, a short wavelength to cleanly ablate the polymer and optimized process parameters and environment.
These short and ultrashort pulse
lasers are found in many micro applications, such as cutting metal and polymer stents, drilling precisely tapered holes, micro welding, and ablation.
Measurements using very tiny crystals have now become feasible thanks to the extreme intensity of FELs whose ultrashort pulse
durations outrun most radiation damage effects.
Among the topics are emerging pulsed laser deposition techniques, fabricating periodic photonic microstructures by the interference of ultrashort pulse
laser beams, the laser-induced soft matter organization and microstructuring of photonic materials, laser-assisted polymer joining methods for photonic devices, and femtosecond-laser-induced refractive index modifications for photonic device processing.
laser ablation of polycarbonate and polymethylmethacrylate.
Illustrating the discussion utilizing MATLAB models, the authors describe the fundamental principles of the generation of ultrashort pulses
employing fiber ring lasers that incorporate active optical modulators of amplitude or phase types; present experimental techniques for the generation, detection, and characterization of ultrashort pulse
sequences; describe the multiplication of ultrashort pulse
sequences using the Talbot diffraction effects in the time domain via the use of highly dispersive media; discuss the theoretical and experimental development of multiple short pulses in the form of solitons binding together by phase states; and describe the generation of short pulse sequences and multiple wavelength channels from a single fiber laser.
These experimental results have been achieved through integration of Tohoku University's fundamental technology on ultrashort pulse
lasers (Tohoku University is promoting joint research program for industry-academic collaboration based on materials and devices), and Sony's fundamental technology on semiconductor laser diodes.
Bosch is using ultrashort pulse
laser technology to manufacture common-rail diesel injectors and emission sensors.
In a first-of-its-kind test, tissue engineers will utilize a new type of laser developed on the Raydiance Ultrashort Pulse
(USP) laser platform to maximize the transplants processed from donated dermal tissue, the company said in a press release.
Kohler and two of his graduate students took portions of the DNA molecule called nucleosides, placed them in water, and then bombarded them with an ultrashort pulse
of UV light from a laser.
