Toward higher-order passive harmonic mode-locking of a soliton fiber laser.
We report >13 MHz/mW pump power efficiency in increasing the repetition rate of passive harmonic mode-locking by engineering the soliton pulse energy in Er fiber lasers incorporating carbon nanotube saturable absorber. Stable pulses with a ∼5 GHz repetition rate and 40 dB of super-mode suppression are demonstrated with only ∼400 mW pump power in a single-clad fiber laser.
متن کاملSaturable Absorber Mirrors For Passive Mode-locking
Saturable absorber mirrors (SAMs) are grown by low-temperature solid-source molecular beam epitaxy. The nonlinear absorber layer consists of one InGaAs quantum well. The devices have response times shorter than 10 ps and small non-saturable losses (less than 0.3%). SAMs with modulation depths between 0.6% and 2.0% were used to mode lock a Yb:KYW laser at around 1040 nm. The minimum achievable p...
متن کاملSelf-starting of passive mode locking.
It has been recently understood that mode locking of lasers has the signification of a thermodynamic phase transition in a system of many interacting light modes subject to noise. In the same framework, self starting of passive mode locking has the thermodynamic significance of a noise-activated escape process across an entropic barrier. Here we present the first dynamical study of the light mo...
متن کاملStatistical light-mode dynamics of multipulse passive mode locking.
We study the multipulse formation in passive mode locking in the framework of the statistical light-mode dynamics theory. It is a many-body theory that treats the complex many-mode laser system by statistical mechanics. We give a detailed theory and experimental verification for the important case of multiple-pulse formation in the laser cavity. We follow and extend our former work on the subje...
متن کاملQ-switching stability limits of continuous-wave passive mode locking
The use of a saturable absorber as a passive mode locker in a solid-state laser can introduce a tendency for Q-switched mode-locked operation. We have investigated the transition between the regimes of cw mode locking and Q-switched mode locking. Experimental data from Nd:YLF lasers in the picosecond domain and soliton mode-locked Nd:glass lasers in the femtosecond domain, both passively mode l...
