RPMC Lasers offers one of the widest wavelength selections of <300 picosecond and >300 picosecond lasers available ranging from the UV through the SWIR regimes. The fundamental beam at 1032nm is also available. AMPHOS offers ultrafast lasers. Therefore, the narrower bandwidths ofpicosecondlasers represent a remarkable advantage over theirfemtosecondcounterparts. It thus also belongs to the category of ultrafast lasers or ultrashort pulse lasers. Pico lasers that produce less than 10 picoseconds pulses belong to the category of ultrafast lasers or ultrashort pulse lasers. 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. Based on an all-fiber design, MPBCs picosecond mode-locked fiber lasers are highly reliable (10,000 hrs) and maintenance-free. 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. Below are two examples of micro-structured patterns in a Platinum Iridium alloy sample that were ablated using IPGs YLPF 10uJ/pulse sub 500 femtosecond pulse width laser.

These ultrafast lasers combines the reliability, low maintenance, high stability, and long lifetime required for 24/7 industrial use. Commercial picosecond medical lasers do not actually achieve this short of a pulse. In such cases, picosecond lasers are often preferred. AMI's proprietary technology allows industry-leading adjustable pulse width performance from 100 ps to over 750 ps at up to 3.0 Amp. Typically, nanosecond pulses are too long, as there is a significant build up of heat in the surrounding material, causing a more prominent heat affected zone (HAZ), which can damage, warp, burn, or discolor the surrounding area. Integrated Control Electronics. Femtosecond USP Lasers Cut, scribe, or drill any material with unmatched edge quality and low (<10 m) HAZ. 15a), and the second one is regular continuous wave (CW) laser (Fig. Koheras single-frequency lasers offer narrow linewidth and extremely low phase- and intensity noise levels. High peak powers, with relatively low energy and heat generation, allows efficient ablation and non-linear interaction with most materials. Picosecond lasers used for tattoo removal require fewer treatments, cause fewer side effects, and result in reduced post-procedural downtime compared to nanosecond Q-switched lasers.

Laser micromachining applications often benefit from that extremely high quality results provided by femtosecond pulses. 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 efficient coupling of the laser energy with the clusters media and subsequent ionization, studies have suggested the significant role of laser pulse duration. The wavelength tuning of the ps laser is fully automated across a tuning range of 700 to 990nm (signal) and 1080 to 1950nm (idler).

Supply Voltage, Single-phase 50-60 Hz, VAC, "Cold process" reduced melt and HAZ, less recast metal, Fewer micro-cracks and better ablated surface quality, Absorption is less material/wavelength dependent. The same is true for femtosecond lasers. A common application is the removal of tattoos, and similarly one may reduce pigments of natural origins. Depending on their wavelength, picosecond lasers are particularly useful for clearing blue and green pigments, which are difficult to eliminate using other lasers, and tattoos that are refractory to treatment with the traditional Q-switched lasers. The additional cost and reduced availability of picosecond lasers compared to Q-switched lasers currently restricts their widespread use.

Here you can submit questions and comments. Common features are a high beam quality, narrow spectral bandwidth, burst mode features and flexibility concerning the pulse duration. Tattoo removal generally works, but some tattoos are much harder to remove than others. Raman-based spectroscopy, being a nonlinear process, usually requires ultrashort pulse generation (e.g., practical TPA set-ups usually require < 300 fs pulse duration). Further laser-guided lightning campaigns will be necessary to fully understand how this giant frickin' laser did the job. 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.

Microchip Lasers: Fully Integrated Modules for LIDAR & 3D Scanning, Laser Induced Breakdown Spectroscopy (LIBS) in Biomedical Applications. As a result, the vast majority of LIBS lasers areq-switched diode pumped solid state (DPSS) lasers, which typically provide millijoules of energy in ananosecondtopicosecondpulse duration. This rapid access to accurate data provides time to adjust the blade angle to optimize the efficiency without overloading the turbine. You must consider both the time delay (Td) and a time jitter (Tj), which is a statistical variation of the time delay depending mostly on: Because of the jitter phenomena, the actual value of the time delay isstatisticallyaltered. Peak powers of tens of kilowatts (or even 160kW at 1064nm) are generated. Therefore, a precise estimation of the laser peak power, given other operational parameters such as average power, pulse duration, and repetition rate, is fundamental to select the best option for a particular application among the different commercial alternatives. This laser series specifically designed to allow for ergonomic and user-friendly operation. Sorry, we don't have an article for that keyword! The picosecond pulsed sources are either laser diode based or LED based devices that can be operated at variable, user-adjustable repetition rates up to 100 MHz. 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.
