Optically-pumped saturable absorber for fast switching between continuous-wave and passively mode-locked regimes of a Nd:YVO4 laser [PDF]

, 2009
We report on the fast (~50 μs) remote-controlled switching between continuous-wave (cw), cw mode-locked (ML) and Q-switched ML modes of operation of a Nd:YVO4 laser using an optically-pumped saturable absorber (SA).

Passively Q-switched Yb-doped fiber laser based on Ag nanoplates saturable absorber [PDF]

EPJ Web of Conferences, 2020
We experimentally investigated Ag nanoplates as saturable absorber for Q-switched pulse generation in an Yb-doped fiber laser. The pulse train repetition rate increases with the increase of the pump power. At the maximum pump power of 600 mW, the maximum

Tunable Gold Nanorods Q-Switcher for Pulsed Er-Doped Fiber Laser

IEEE Photonics Journal, 2017
We prepared the gold nanorods (GNRs) via seed-mediated growth method, and fabricated the fiber-compatible saturable absorption device with it. We found that the nonlinear absorption behavior of the fiber-compatible GNRs saturable absorber can be tuned by

On Two Models of the Light Pulse Delay in a Saturable Absorber

, 2011
A comparative analysis of two approaches to description of the light modulation pulse delay in a saturable absorber is presented. According to the simplest model, the delay of the optical pulse is a result of distortion of its shape due to absorption ...

Coherent instabilities in a semiconductor laser with fast gain recovery [PDF]

, 2006
We report the observation of a coherent multimode instability in quantum cascade lasers (QCLs), which is driven by the same fundamental mechanism of Rabi oscillations as the elusive Risken-Nummedal-Graham-Haken (RNGH) instability predicted 40 years ago ...
