A picosecond laser is a type of laser that emits pulses of light with a duration of one picosecond (10^-12 seconds). If you don't see a laser with the parameters needed, most of our lasers can be modified for your needs. Picosecond lasers use pulse durations of less than 1 nanosecond, which causes predominantly photoacoustic damage (pulses of light that can be measured by changes in pressure ie, sound waves) rather than photothermal destruction of pigment or ink particles (measured by production of heat). The skies were clear enough for high-speed cameras to capture the lightning strike, which appeared to follow the laser for around 50 meters (approximately 165 feet). Professional and multicolored tattoos are cleared in far fewer treatment sessions than with conventional Q-switched lasers. Raman-based spectroscopy, on the other hand, is an entirely different nonlinear technique, relying on the frequency shift experienced by laser radiation incident on a molecule, related to its rotational and vibrational modes. For such purposes, compact and cheap lasers with gigahertz repetition rates, often with emission in the 1.5-m telecom bands, are required. In such cases, picosecond lasers are often preferred. Our monolithic-all-spliced-fiber design is "beyond state-of-the-art", enabling an incredibly compact laser that is inherently more power efficient, reliable and robust than conventional bulk-rod or disk . 1400 - 16000 nm (7000 - 625 cm-1) tuning range; Linewidth <5 cm-1 in the full tuning range; Nearly diffraction limited divergence; . The main indication for the use of a picosecond laser is tattoo removal [1]. The images above show a 380 micron diameter circular and rectangular cuts in a polyimide film. Alternatively, implementing a network of single-frequency Doppler LIDAR sensors around a wind farm, in conjunction with highly accurate wind models, allows for much higher accuracy wind speed readings and faster response times. Shorter pulsed durations and higher pulse energies are available upon request.
