Mode-locked multichromatic x rays in a seeded free-electron laser for single-shot x-ray spectroscopy

Physical Review Special Topics. Accelerators and Beams, 2012
We present the promise of generating gigawatt mode-locked multichromatic x rays in a seeded free-electron laser (FEL). We show that, by using a laser to imprint periodic modulation in electron beam phase space, a single-frequency coherent seed can be ...

Efficient Wavelength-Tunable Gain-Switching and Gain-Switched Mode-Locking Operation of a Heavily Er³⁺-Doped ZBLAN Mid-Infrared Fiber Laser

IEEE Photonics Journal, 2017
We report on an efficient wavelength-tunable gain-switched and gain-switched mode-locked Er3+-doped double-clad fiber laser with a linear cavity. Stable gain-switching and gain-switched mode-locking were achieved with slope efficiencies of 28.6% and 34.5%

Mode Locked Fiber Lasers

, 2013
Nowadays, to satisfy the increase of internet demands and requirement, two multiplexing techniques are used: WDM (Wavelength Division Multiplex) and TDM (Time Division Mul‐ tiplex). WDM still more used than TDM. However, for practical system applications, such as optical CDMA (Code Division Multiplex Access) and OTDM (Optical Time Division Multi‐ plex)

Passively Mode-Locked Erbium-Doped Fiber Laser and Application in Laser Thrombolysis

Photonics
Fiber lasers have been widely used in surgery with the development of fiber photonics. Since the human body is prone to myocardial infarction caused by blood clots, laser thrombolysis was proposed as a safe and efficient treatment.
