Picosecond pulses are also often used in pumpprobe measurements on timescales of multiple picoseconds to nanoseconds. Which means NASA's next moon mission might not have to be so afraid of that nasty Florida weather. The basic design and idea behind a lightning tower hasn't changed much since its invention in the 18th century. Second, third, fourth and fifth (on some versions) harmonic options combined with various accessories, advanced electronics (for streak camera synchronization, phase-locked loop, synchronization of fs laser) and customization possibilities make these lasers well suited for many scientific applications, including optical parametric generator pumping, time-resolved spectroscopy, nonlinear spectroscopy, remote sensing, metrology and others. The use of picosecond lasers has also been reported for treatment of melasma, naevus of Ota, naevus of Ito, minocycline-induced pigmentation, and solar lentigines [2]. They cover discrete wavelengths from 255 nm to 1990 nm. There are also surgical procedures where precise material ablation can be achieved with picosecond pulses. In applications such as laser micromachining, one sometimes achieves better quality results with femtosecond pulses, but picosecond pulses are often sufficient when the process is sufficiently optimized overall. For example, distance measurements with LIDAR, e.g. The main indication for the use of a picosecond laser is tattoo removal [1]. By assuming a train of continuously repeated, periodical, square pulses with repetition rate fR, pulse duration tP and average power PAV, the pulse energy EP and peak power PP calculations are trivial, with pulse energy provided by the ratio between average power and repetition rate and peak power provided by the ratio between energy and pulse duration: In actively Q-switched lasers, the user controls the pulsed laser output, so that no laser pulse emission occurs without providing a proper input signal, aka the trigger. High power picosecond laser Versatile high-power, sub-nanosecond pulsed laser system designed for all industrial applications. The all-fiber DFB design ensures robust and reliable operation for thousands of hours. In this process, a microscopic portion of the sample is vaporized causing a momentary plasma to be formed. Short picosecond pulses are ideal for creating high contrast black marks or barcodes on metals such as stainless steel and aluminum. Trigger Output for Pulse Monitoring. Laser pulses with durations of just a few picoseconds create peak intensities so high that non-linear/multiphoton absorption takes place, resulting in an ultra-precise cold process with very small heat affect - making them ideal for applications in micromachining, surface structuring, thin film ablation, thin foil or polymer cutting, dark marking of metals and processing of brittle or transparent materials. However, short picosecond pulses often provide perfectly acceptably results when the processing parameters are optimal, making picosecond lasers the preferred choice, if you do not require the ultra-fine features and exceptional edge quality that femtosecond lasers provide. As the name implies LIBS utilizes a focused laser beam to breakdown or ablate the sample. We group our picosecond lasers into a few different types including Pulsed DPSS Lasers, Pulsed Fiber Lasers, Ultrafast Lasers, Microchip Lasers, and DPSS Amplifiers.
