Harnessing Air to Bend and Deflect Laser Beams

Originally Published 2 years ago — by Phys.org

Researchers have developed a novel method to deflect laser beams using air alone. By modulating the air with sound waves, an optical grating is created that changes the direction of the laser light. This technique allows for precise control of laser beams without contact, preserving their quality. In initial tests, a strong infrared laser pulse was redirected with 50% efficiency, and higher efficiencies are expected in the future. The researchers see potential applications in high-performance optics, where traditional optical elements are limited by material properties and susceptibility to damage from strong laser beams.

"Groundbreaking Achievement: Researchers Unveil Visible Wavelength Femtosecond Fiber Laser"

Originally Published 2 years ago — by Phys.org

Researchers have developed the first fiber laser capable of producing femtosecond pulses in the visible range of the electromagnetic spectrum. The laser, based on a lanthanide-doped fluoride fiber, emits red light at 635 nm and achieves compressed pulses with a duration of 168 fs. This breakthrough paves the way for reliable, efficient, and compact ultrafast lasers that could have applications in biomedical fields such as high-precision tissue ablation and two-photon excitation microscopy, as well as in material processing.
