Background and aims: Recently novel picosecond duration lasers (ps-lasers) have been developed for the treatment of multicolored and recalcitrant tattoos, and safety and efficacy have been reported. A picosecond laser selectively destroys the target pigment without damaging healthy, normal tissue. This results in effective clearance of abnormal pigment, while minimising photothermal damage to the surrounding tissue. 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. Please submit your photosof this topic for inclusion. The thickness of one of these disks (typically 150m to 200m thick) is substantially smaller than the beam diameter. info@picoquant.com, Check out our live and on demand webinars, Dual calibration - max power and linear mode, High power multimode diodes in Vis and NIR, Repetition rate from single shot to 100 MHz. Pulse width: 8ns. 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. using "RP Enc" instead of "RP Photonics Encyclopedia". Copy edited by Gus Mitchell/Maria McGivern. During observation, the comms tower was hit at least sixteen times, with four of those happening during laser activity. This is typically done using a multi-beam approach, which takes advantage of the difference in absorption of the water at various wavelengths. The high peak power and short pulse widths (pulse duration) of these lasers are ideal for a wide range of applications especially for material processing and micromachining industrial applications such as laser texturing, trimming, and drilling.

Why is a Low Jitter Feature Important in Actively Q-Switched DPSS Lasers? Picosecond pulses can be produced from diode-pumped solid-state (DPSS) lasers, fiber lasers, and microchip lasers allowing for an extensive wavelength range from the ultraviolet through the infrared region. RPMC Lasers is your preferred Picosecond Laser Supplier, partnering with industry-leading and emerging manufacturers. (See also our privacy declaration.) Output pulse amplitude and width are user adjustable via on-board potentiometers, while repetition frequency follows an external trigger signal from single shot up . 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. Katana is streamlined to offer high-power picosecond pulses in green, yellow, orange, red, and infrared. AMI's proprietary technology allows industry-leading adjustable pulse width performance from 100 ps to over 750 ps at up to 3.0 Amp. Notably, infrared thermography analysis showed that temperature increase of the cells during the irradiation was within 1 K, excluding thermal damage of cells. Power levels vary between W and hundreds of mW for the most powerful, fibre amplified versions.

That way, you can open it with a single click. In case you find the bookmark entry too long, you can right-click it to edit the text, e.g. A picosecond laser is a laser device that uses very short pulse durations to target endogenous pigmentation and exogenous ink particles (tattoos). The new, ultrafast NPS Series features up to 10W average output power, <7ps pulse width, and a 40MHz repetition rate. The output specifications can be chosen according to our customers needs, mainly by choice of the seed laser (multiple seed lasers are possible) and various options available. The ALPHALAS product line of PICOPOWER series ultrafast lasers implements advanced methods for generating picosecond pulses, including active, passive or combined mode-locking. While a wide variety of single-frequency lasers have been used in Doppler LIDAR research, the industry as a whole has adopted picosecond and short-nanosecond pulsed, single-frequency fiber lasers as the ideal light source. Compatible with 30 mm Cage System. Average output powers for these picosecond laser options range from a few mW (milliwatts) up to 150 W (watts), and pulse energy options ranging from 25 nJ (nanojoules) up to 150 mJ (millijoules). Finally, check out our Limited Supply In Stock Buy Now page: This page contains an ever-changing assortment of various types of new lasers at marked-down/discount prices. 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.

Compared with mode-locked picosecond lasers, the pulse repetition rates are limited to about 100kHz), while the pulse energies are far higher tens of microjoules. The KATANA HP is a versatile high-power, sub-nanosecond pulsed laser system designed for industrial applications. Some picosecond lasers have fractionated hand pieces that facilitate tissue remodelling and are used to treat acne scarring, photoageing, and rhytides (wrinkles) [2]. Forbat E, Al-Niaimi F. The use of picosecond lasers beyond tattoos. 1400 - 16000 nm (7000 - 625 cm-1) tuning range; Linewidth <5 cm-1 in the full tuning range; Nearly diffraction limited divergence; . Second Harmonic (532 nm output) and wavelength conversion option widen the product application range. Fine features can be machined in a broad range of materials using Ultra-Short Pulsed lasers with sub 10 picosecond pulse durations. Power levels vary between W and hundreds of mW for the most powerful, fibre amplified versions. 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. via social media: These sharing buttons are implemented in a privacy-friendly way!

This increased HAZ is undesirable, as post processing (cleaning) is then required, and furthermore, depending on the requirements and specifications of the material or product, significant heat build up can cause catastrophic failure of the part, its particular features, or simply render it unusable, for example with medical products that need clean, smooth features.
