The company was founded 1975 in Hamburg, Germany as "SINAR Laser Systeme Verkaufsgesellschaft mbH". Sinar is the Sanskrit for "beam of light", but this name was already used by a Swiss manufacturer of cameras. By taking over the British enterprise Rofin, the company changed its name to ROFIN-SINAR Laser GmbH. [4]

Mode locking is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds (10 −12 s) or femtoseconds (10 −15 s). A laser operated in this way is sometimes referred to as a femtosecond laser, for example, in modern refractive surgery.
Radio over fiber (RoF) or RF over fiber (RFoF) refers to a technology whereby light is modulated by a radio frequency signal and transmitted over an optical fiber link. Main technical advantages of using fiber optical links are lower transmission losses and reduced sensitivity to noise and electromagnetic interference compared to all-electrical signal transmission.
Laser ablation or photoablation (also called laser blasting [1] [2] [3]) is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates .
Self-focusing in a plasma can balance the natural diffraction and channel a laser beam. Such effect is beneficial for many applications, since it helps increasing the length of the interaction between laser and medium. This is crucial, for example, in laser-driven particle acceleration, [32] laser-fusion schemes [33] and high harmonic ...
Authorities battling a series of large wildfires in the Los Angeles area have employed a bright red fire retardant to tamp the flames, leading to dramatic images of the material blanketing scores ...
