Self-starting self-similar all-polarization maintaining Yb-doped fiber laser

Self-starting self-similar all-polarization maintaining Yb-doped fiber laser.

We report on the generation of self-similar pulses from an self-starting saturable absorber mirror (SAM) based environmentally stable fiber laser comprising only polarization maintaining (PM) fibers. Pulse energies of 1 nJ at a repetition rate of 17 MHz were obtained, which could be externally compressed to an autocorrelation width of 280 fs.

All-Fiber Bismuth Doped Self-Sweeping Laser

Figure 1: Laser wavelength dynamics The effect of self-induced laser line sweeping (or self-sweeping) was discovered in ruby laser in 1962 [1]. It was considered as an undesirable effect due to a small sweeping range. In fiber lasers the effect with broad sweeping range (more than 10 nm) was observed almost 50 years later [2]. The self-sweeping effect is caused by the formation of dynamical pha...

The all-fiber cladding-pumped Yb-doped gain-switched laser.

Gain-switching is an alternative pulsing technique of fiber lasers, which is power scalable and has a low complexity. From a linear stability analysis of rate equations the relaxation oscillation period is derived and from it, the pulse duration is defined. Good agreement between the measured pulse duration and the theoretical prediction is found over a wide range of parameters. In particular w...

Self-starting low-noise fiber soliton laser.

We report a self-starting passively mode-locked soliton source generating 1-ps-wide pulses. The laser is configured as a ring with an erbium-doped fiber gain medium, a length of conventional fiber that provides the required dispersion and Kerr nonlinearity, and an intracavity multiple-quantum-well optical amplifier that serves as a saturable absorber and pulse stabilizer. The laser exhibits low...
