Optical parametric chirped pulse amplification is a promising approach for amplifying few-cycle laser pulses to unprecedented powers. However, the future success of the scheme depends on the ...

Abstract: We propose a distributed acoustic sensing technique that utilizes correlation analysis derived from short-chirped-pulse optical frequency-domain reflectometry (OFDR). The performance of the ...

They are now a popular tool in applications ranging from materials processing and laser surgery ... products (a measure of pulse complexity), and it tends to introduce chirp, which distorts ...

In this system, the first laser acts like a drill, heating the plasma and forming a channel that guides the following “drive” laser pulse, which accelerates the electrons. The plasma channel directs ...

The HP LaserJet M209d is a sterling value among low-cost, print-only mono laser printers. (If you're considering an inkjet but print only occasionally, it's a tempting alternative.) Its paper ...

Both the excimer laser and the pulsed-dye laser (PDL) effectively treat psoriasis, but which is more effective? In this self-controlled, prospective trial sponsored by the manufacturer of the PDL ...

The Pulse takes you behind the doors of operating rooms, into the lab with some of the world's foremost scientists, and back in time to explore life-changing innovations. The Pulse delivers ...

Some cats will combine vocalizations like grunts and chirps to produce complex sounds. But why do they chirp? There are several fascinating reasons. The most common form of cat chirp comes as a ...

The best color laser printers are a great investment that can save you time and money compared to cartridge-based inkjet printers. Laser printers use toner, which lasts a long time, delivering a ...

Ukraine has developed a laser weapon capable of shooting down targets from more than a mile away, the country’s drone force commander has claimed Speaking at a defense summit in Kyiv this week ...
