“…However, Q-switched mode-locking, multiple-pulsing, and cwbreakthrough instabilities prevented us from obtaining stable cw-mode-locked operation with shorter pulses. We believe that this is due to the lower emission cross section of the Cr:LiCAF gain media [19], which results in a very narrow SBR mode-locking ranges for sub-50-fs pulses [35]. …”

We present a detailed experimental study of femtosecond tuning with Cr:LiSAF and Cr:LiCAF gain media using Al 0:95 Ga 0:05 As=Al 0:17 Ga 0:83 As-based saturable Bragg reflectors. In the experiments with Cr:LiSAF gain media, femtosecond tuning ranges of 803-831 nm (28 nm), 828-873 nm (45 nm) and 890-923 nm (33 nm) were demonstrated using three different saturable Bragg reflectors with reflectivity bands centered at around 800, 850, and 910 nm, respectively. With Cr:LiCAF gain medium, a femtosecond tuning range of 767-817 nm (50 nm) was demonstrated using the 800 nm saturable Bragg reflector. Pulses as short as 26 fs with Cr:LiSAF and 39 fs with Cr:LiCAF have been obtained, which we believe are the shortest pulses reported from Cr:colquiriite laser systems mode locked with saturable Bragg reflectors. This study further illustrates the benefits and limitations of Al 0:95 Ga 0:05 As=Al 0:17 Ga 0:83 As-based saturable Bragg reflectors for use in Cr:colquiriites.

“…In particular, analytical estimations for the stability criteria for cw ML regime in a solid state laser were obtained [2,4]. However, since previous theoretical studies were based on the Haus master equation, which assumes small gain and loss, their results are hardly applicable to describe Qswitching bifurcation in the parameter range typical of semiconductor lasers.…”

Q-switching instability in a mode-locked semiconductor laser

We suggest analytic estimates for the Q-switching instability boundary of the continuous-wave mode-locking regime domain for a ring cavity semiconductor laser. We use a differential delay laser model that allows to assume large gain and loss in the cavity, which is a typical situation for this laser class. The slow saturable absorber approximation is applied to derive a map that describes the transformation of the pulse parameters after a round trip in the cavity. The Q-switching instability boundary is then obtained as a Neimark-Sacker bifurcation curve of this map. We study the dependence of this boundary on laser parameters and compare it with the boundaries obtained by New's stability criterion and by direct numerical analysis of the original delay differential model. Further modification of our approach, based on the hyperbolic secant ansatz, is used to estimate the width and repetition rate of the mode locking pulses.

“…The dynamics of a SESAM mode-locked laser can be described in very good approximation by three differential equations [10][11][12], for the temporal dynamics of the pulse envelope, the laser gain and the absorber loss. The master equation of mode-locking, describing the evolution of the pulse's envelope reads …”

Abstract:The pulse shaping dynamics of a diode-pumped laser oscillator with cavity dumping operating in the solitary regime is studied experimentally and numerically. The stability of the laser system is investigated in dependence on the relevant laser parameters. With a stroboscopic detection technique the intracavity temporal and spectral pulse profiles are measured between two dumping events. The results are compared to the numerical analysis of the system. Due to the strong periodic disturbance of the solitary pulse imposed by the dumping process a second set of Kelly-side bands can be identified.
