We show theoretically and experimentally how the damping of the relaxation oscillations is reduced and finally becomes zero when the pump power is reduced so that the threshold for Q-switched mode locking is approached. For the first time to our knowledge, this method provides important information...
5.1. It is seen that the carrier density at the front of the pumping pulse passes the threshold value at a certain time t0, at which point the net gain in the laser becomes positive and the photon density starts growing from a small seed provided by the spontaneous emission. However, ...
Second threshold condition in the case of Q switching by self-focusing In a recent paper (Opt. Lett. 10,, 402 (1985)) we presented a novel passive technique for obtaining giant laser-pulse emission. In this paper we present a ... MC Marconi,OE Martinez,FP Diodati - 《Journal of the ...

The EDFL generates a Q-switching pulse operating at 1557.6 nm at a threshold pump power as low as 20.0 mW. The Q-switching operation is maintained before disappearance when the pump power is above 33.7 mW. This is due to the fact that the TDF SA could not fully recover in time after ...

Recent studies of monomode silica fibre which has rare-earth impurity ions incorporated into the core region have shown that it can exhibit laser action with low threshold and high efficiency when end pumped by an external laser source. ... IP Alcock,AC Tropper,AI Ferguson,... - Optoelectroni...
In this paper, the threshold behaviours of the self-pulsing instability for the class B lasers with saturable absorber are studied. 对含有可饱和吸收体的B类激光系统的自脉冲不稳定性的阈值行为进行了研究,并就各种激光参量对其阈值的影响进行了数值计算。 3. The numerical method is used to solve the...
II. Temperature Dependence of Threshold Current and Excitation Dependence of Superradiance Spectra The spontaneous and stimulated emission spectral functions are calculated using a band model consisting of the self-consistent densities of states calculated in a previous paper and an optical model with an ...
