Short picosecond pulses are ideal for creating high contrast black marks or barcodes on metals such as stainless steel and aluminum. Here are the latest encyclopedia articles: The encyclopedia already contains 1020 articles. A common application is the removal of tattoos, and similarly one may reduce pigments of natural origins. Sometimes, the whole setup is still called a picosecond laser, even though it also contains an OPO. Further laser-guided lightning campaigns will be necessary to fully understand how this giant frickin' laser did the job. That way, you can open it with a single click. For instance, it wouldn't seem wise to use a laser around an active air field -- and the researchers note in their methods they only operated this particular laser when airspace was closed. Ytterbium Picosecond Pulsed Laser. Power levels vary between W and hundreds of mW for the most powerful, fibre amplified versions. Ideal for micromachining, fine cutting and precision LIDAR, all the models are enclosed in an extremely compact and ruggedized single unit with both air-cooled and water-cooled options available. The additional cost and reduced availability of picosecond lasers compared to Q-switched lasers currently restricts their widespread use. 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. laser drilling or cutting, it is often advantageous to use very short light pulses having correspondingly high peak powers for a given pulse energy. 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.
