Pulse fidelity control in a 20-μJ sub-200-fs monolithic Yb-fiber amplifier

Abstract

Abstract-We discuss nonlinearity management versus energy scalability and compressibility in a three stage monolithic 100 kHz repetition rate Yb fiber amplifier designed as a driver source for the generation and tun able parametric amplification of a carrier envelope phase stable white light supercontinuum.

Polarization-maintaining amplification of phase modulated pulse employing ytterbium-doped single-mode fiber amplifier

“…Picosecond or femtosecond laser pulse output is achieved in mode locked fiber lasers with novel con figurations or novel devices [1][2][3][4][5]. To maintain the shape of the broadband pulse laser, novel gain flat tened fiber laser configurations and methods have been proposed [6][7][8].…”

All-fiber millijoule energy and nanoseconds pulse operation of a high beam quality multi-stage pulse-pumped Yb-doped amplifier cascade

“…Nowadays, lasers have developed more and more rapidly, including continuous and pulsed lasers [1][2][3][4][5][6][7][8][9][10][11][12]. Numerous applications of lasers require optical pulses with high beam quality, milliJoule pulse ener gies, and nanosecond pulse durations, such as materi als processing [13], remote sensing [14](chemical and physical), and nonlinear frequency conversion [15].…”

Effective pulse recompression after nonlinear spectral broadening in picosecond Yb-doped fiber amplifier

“…But, high power short pulse fiber lasers suffer from the onset of unwanted nonlinear effects, like self phase modulation or stimulated Raman scattering, which limit the maximum output power and degrade output pulse shape and duration. An ultra short pulse may cause even supercontinuum generation in fiber [7][8][9]. Recently, the photonic crystal fiber (PCF) with tech nical design is able to overcome these problems in the traditional double cladding (DC) fiber [10][11][12].…”
