The picosecond laser benefits make them a good fit for many applications. With around 40 to 120 lightning strikes occurring every second on Earth, there's a decent chunk of area, infrastructure and human life that needs protecting. One thing most of these applications share is the benefit of utilizing very short light pulses in the picosecond and short nanosecond range (as well as femtosecond for certain applications), which provide high peak power for a particular pulse energy. The KATANA HP is a versatile high-power, sub-nanosecond pulsed laser system designed for industrial applications. The main indication for the use of a picosecond laser is tattoo removal [1]. The PICOPOWER-LD series of the proprietary picosecond diode lasers covers the range 375 nm to 2300nm with picosecond pulses as short as 12ps and high peak power more than 2W for specific wavelengths. laser pulse build-up time-mechanism and associated fluctuations. Thus, femtosecond fiber lasers will not produce heat affected zones (HAZ), splatter, or significant recast. Cue the Dr. Picosecond laser therapy is mainly well tolerated. Based on an all-fiber design, MPBCs picosecond mode-locked fiber lasers are highly reliable (10,000 hrs) and maintenance-free. Laser micromachining applications often benefit from that extremely high quality results provided by femtosecond pulses. Output pulse amplitude and width are user adjustable via on-board potentiometers, while repetition frequency follows an external trigger signal from single shot up . In this process, a microscopic portion of the sample is vaporized causing a momentary plasma to be formed. These results indicate that the picosecond pulsed infrared laser can safely reduce amyloid fibril structure to the nonfibril form even in cells. Picosecond Diode Lasers, Pico-LDs, are designed and manufactured by CrystaLaser. Why is a Low Jitter Feature Important in Actively Q-Switched DPSS Lasers? They cover discrete wavelengths from 255 nm to 1990 nm. Not being related to electronic transitions, theRamanshift is relative concerning the irradiating wavelength, and therefore, unless pursuing coherent excitation, laser source tunability is not required. As can be seen in the graph below, water has an absorption minima around 500 nm, meaning that green laser light will penetrate much deeper into the water than near-infrared light will. 415103008, 443187002, 468974003, 468865001, neodymium-doped yttrium aluminium garnet (Nd:YAG). 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. This is done by using a time-gated detector which is synchronized with a pulsed (typically picosecond or short-nanosecond range) laser source so that the round-trip time (t) can be determined. We therefore hypothesized that the ps-laser could be an alternative treatment for dermal pigmented lesions and performed a retrospective review to evaluate the efficacy and safety of the ps-laser. For example, theVaryDisk Series platform is a high energy, multi-milli-Joule laser system for laboratory investigations or industrial use. Common features are a high beam quality, narrow spectral bandwidth, burst mode features and flexibility concerning the pulse duration. As in mostLIDAR systems designed for distance measurement, bathymetric LIDAR relies on time-of-flight determination for calculating the distance to the target.
