For example, distance measurements with LIDAR, e.g. It doesn't always travel from a cloud to the ground, either. Between July and September of that year, the picosecond laser -- which fires at around 1,000 pulses every second, was operated for more than 6 hours of thunderstorm activity. Therefore, opening the way to nonlinear optics applications like OPO pumping, and narrowband Raman Spectroscopy. (FREE) Post a PDF data sheet to our Open-Index product research engine. The compact and lightweight package represents a great benefit in LIDAR and other aerospace applications, while short pulses give extremely precise time-of-flight measurements. Average output power varies from 2 to 3000mW, depending on the configuration. Our offerings include pulsed DPSS lasers, fiber lasers, and microchip lasers with pulse energy as high as 5mJ and pulse repetition rates up to 80MHz. Excellent beam quality enables very small spot sizes and therefore, high peak power, incident upon the sample, for high-quality data collection.

Imprint dermabrasion. It thus also belongs to the category of ultrafast lasers or ultrashort pulse lasers. For example, picosecond lasers may be used for generating soliton pulses in optical fibers, which propagate without dispersive broadening. 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. Join our mailing list to receive the latest news about upcoming events and webinars, our latest developments as well as company news. Internal trigger >25 Hz. 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. Pulse widths can be as short as 40ps. The picosecond laser benefits make them a good fit for many applications. Shorter pulsed durations and higher pulse energies are available upon request.

Thus, femtosecond fiber lasers will not produce heat affected zones (HAZ), splatter, or significant recast. Your email address will be processed in accordance to our privacy policy. The main indication for the use of a picosecond laser is tattoo removal [1]. They are ideal for precision micromachining applications such as processing of semiconductors, Due to the trigger signal propagation through the interface electronics, the Q-switch driver chain, and the laser resonator build-up time, a time delay (Td) is present between the externally-supplied trigger signal and the actual laser pulse emitted by the laser source. We have investigated the effect of laser pulse repetition rate (0.2-8.2 MHz) and fluence (0.079-1.57 J cm 2) on the morphology, crystallinity and stoichiometry of the films.X-ray diffraction, energy dispersive X-ray spectroscopy and Rutherford backscattering spectroscopy . We have fielded 1000s of units for many different applications from micromachining to LIDAR and Bathymetry to medical applications such as tattoo removal and ablation-based surgical procedures. (Yes, lightning does strike twice and sometimes more than that.). If you want to place a link to this article in some other resource (e.g. Some of these lasers are industrial lasers, while others are scientific lasers. Note: this box searches only for keywords in the titles of encyclopedia articles. Operating mode Pulsed. The devices from most manufacturers deliver pulses that are actually several hundred picoseconds or just under one nanosecond, a billionth of a second, 10 -9 s. 1) Pulse-on-demand with external trigger. Lightning is a complicated phenomenon, caused by an imbalance in positive and negative charges between storm clouds and the ground.

As with other laser devices, picosecond lasers are relatively contraindicated in patients with darker skin tones (ie, Fitzpatrick skin types 46), who are more susceptible to side effects from laser treatment. A thin disk laser is a type of diode-pumped solid-state (DPSS) laser technology in which the gain medium is comprised of a thin disk of typically Yb:YAG crystal. This results in effective clearance of abnormal pigment, while minimising photothermal damage to the surrounding tissue. The novel design architecture and flexible control electronics provide conveniently short warm-up times and allow adjustment of both pulse energy and repetition rate without affecting the output beam parameters. During the storms, the launch zone was hit by lightning four times. Hsu VM, Aldahan AS, Mlacker S, Shah VV, Nouri K. The picosecond laser for tattoo removal.

This laser series offers average powers of 1 to 40W at 1030 nm or 1064 nm (upon request) and can be doubled or tripled in the harmonics to answer even the most challenging industrial and scientific applications. While the primary difference between traditional LIDAR and 3D scanning applications is the distance from the laser to the target, both sets of applications benefit from the features provided by high-quality microchip lasers. Finally, head to our Knowledge Center with our Lasers 101 page and Blogs, Whitepapers, and FAQ pages for further, in-depth reading. SrTiO 3 particle-composed films were grown on Si substrates via picosecond ultrafast pulsed laser deposition. (Please enter the sum of thirteen and three in the form of digits!). In such cases, picosecond lasers are often preferred. Choose from more than 10 different wavelengths in the range from 375-1550 nm, repetition rates from single-shot to 40 MHz pulse trains, internal or external trigger. As the name implies LIBS utilizes a focused laser beam to breakdown or ablate the sample. This feature allows not only the ability to easily scale up power via pump beam diameter, but also provides a large surface area for heat dissipation. Single Housing MIR Tunable Picosecond Laser. The transform-limited operation, with a spectral width of < 0.3nm, and remarkably accurate central wavelength (1064.3 +/- 0.1nm) make the NPS Series a suitable candidate for highly efficient amplification by Nd-doped DPSS amplifiers. A wide range of repetition rate options are available from single shot up to 80 MHz. Modular line card laser and amplifier system. Picosecond laser treatment is mostly well tolerated. A variety of laser types can generate picosecond pulses, with other performance parameters varying in wide ranges: Picosecond lasers are used in a wide range of laser applications. A simplistic design and low cost ensure a long lifetime of reliable performance, with reduced susceptibility to shock and vibration, without breaking your budget. Sometimes, other laser-based sources for picosecond pulses for example synchronously pumped OPOs are also called picosecond lasers, even if they are strictly speaking no lasers.
