Passive mode locking with a hybrid laser
Summaries of Papers Presented at the Lasers and Electro-Optics. CLEO '02. Technical Diges, 2003It has been shown that a hybrid laser, which contains both an inhomogeneously broadened and a homogeneously broadened laser media, can improve the active mode locking performance.1,2 It generates coherent and shorter pulses as compared to that by either the inhomogeneously broadened medium or the homogenously broadened medium alone.

Mode-locked fiber laser gyroscope
Optics Letters, 1993We describe a new form of an all-fiber-optic gyroscope that utilizes a fiber laser. The Sagnac interferometer is used as a loop reflector with a modulated reflectivity to produce actively mode-locked optical pulses. The rotation-induced phase shift is obtained from the timing shift of the pulses.

Self-mode-locked Cr:forsterite laser
Optics Letters, 1993We have demonstrated self-sustaining operation of a mode-locked chromium-doped forsterite laser in which short-pulse formation is entirely due to the nonlinearity of the laser crystal. Stable pulse trains are generated for intracavity pulse energies from 35 to 120 nJ. Pulses less than 100 fs in duration are obtained over the range of 1.23–1.28 μm, with

Optical Engineering, 1992
A review of various types of active and passive mode-locked lasers is presented. Theoretical and experimental aspects of mode locking are covered. Stabilization schemes used in mode-locked laser systems are described. Techniques used in the measurement of the time duration of the ultrashort pulses and the uses of high-power, low-power, and picosecond ...

IEEE Journal of Selected Topics in Quantum Electronics, 2000
The evolution of the theory of mode-locking over the last three and a half decades is reviewed and some of the salient experiments are discussed in the context of the theory. The paper ends with two-cycle pulses of a mode-locked Ti:sapphire laser.

Revisiting the physics of mode locking in lasers
SPIE Proceedings, 2014We present a way to describe mode locking through a master equation, derived from the laser Maxwell-Bloch equations, which take into account coherence in light-gain interaction. Our derivation shows that gain evolution on the fast time scale of the laser pulses must be considered, unlike in Haus master equation.

Mode-locked ytterbium fiber lasers
Applied Optics, 2004A compact fiber laser is demonstrated with use of a Gires-Tournois compensator and a short length (2-4 cm-long) of highly doped ytterbium (Yb) fiber providing net anomalous group-velocity dispersion. With use of a novel semiconductor saturable absorber mirror based on GaInNAs structure, self-started 1.5-ps-pulse mode-locked operation was obtained at ...

Mode-Locking Techniques of Femtosecond Laser
2020 The 9th International Conference on Networks, Communication and Computing, 2020Ultrafast laser is a well-developed technology with its origin dated back to half a century ago, and femtosecond laser, being the type of ultrafast laser with the lowest duration, appeared in a much later stage. The essential technique which made femtosecond laser possible is mode-locking.

Passive mode locking of the Ar^+ laser
Applied Optics, 1988We have studied passive mode locking of the Ar(+) laser using the saturable absorber rhodamine 6G in four different regimes as follows: when the Ar(+) laser operates in the colliding pulse mode locking configuration (1) with and (2) without double mode locking incorporated and also when the Ar(+) laser operates in the conventional configuration (3 ...

The graphene mode-locked fiber laser
SPIE Proceedings, 2011Starting from the structure of graphene, the electrical and optical properties of graphene is analyzed in this paper. Then, the transmission characteristics and the modulation for the optical pulses are discussed with the graphene waveguide model. Finally, the graphene based on the mode-locked fiber laser system is simulated, thereafter the role played
