Tunable picosecond pulse generation from an actively mode-locked laser diode array with Intracavity chirp compensation
1994Co-Authors: Ci-ling Pan, Chi-luen WangAbstract:In this paper, we will present for the first time a tunable picosecond laser system based on a commercial laser diode array using the actively mode-locking technique. The novel feature is the incorporation of a folded dispersive delay line which served the functions of wavelength tuning and Intracavity Dispersion compensation, with good sidemode suppression and spatial mode control.

Passively Mode-Locked Diode Laser With Optimized Dispersion Management
IEEE Journal of Selected Topics in Quantum Electronics, 2015Co-Authors: Jan C. Balzer, Andreas Klehr, Götz Erbert, Günther Tränkle, Benjamin Döpke, Carsten Brenner, Rouven H. Pilny, Martin R. HofmannAbstract:We investigate passively mode-locked diode lasers with external cavity for ultrashort pulse generation. Our strategy to achieve ultrashort pulses is to generate strongly chirped pulses with a maximized bandwidth and to compress them externally. By managing Intracavity Dispersion with an evolutionary algorithm, we obtain pulse widths as short as 278 fs following this approach. We analyze the bandwidth of the optimized pulses in comparison to the available net gain bandwidth of the diode laser device to derive further strategies for achieving shorter pulses.

Mode-locked semiconductor laser system with Intracavity spatial light modulator for linear and nonlinear Dispersion management.
Optics express, 2014Co-Authors: Jan C. Balzer, Andreas Klehr, Götz Erbert, Günther Tränkle, Benjamin Döpke, Carsten Brenner, Martin R. HofmannAbstract:We analyze the influence of second and third order Intracavity Dispersion on a passively mode-locked diode laser by introducing a spatial light modulator (SLM) into the external cavity. The Dispersion is optimized for chirped pulses with highest possible spectral bandwidth that can be externally compressed to the sub picosecond range. We demonstrate that the highest spectral bandwidth is achieved for a combination of second and third order Dispersion. With subsequent external compression pulses with a duration of 437 fs are generated.

A normal-Dispersion fiber with a high numerical aperture and small core was used for Intracavity Dispersion management and external compression. Numerical simulations were performed and are in good agreement with the experimental results.

1993Co-Authors: N. H. Rizvi, Peter J. Delfyett, J.r. Taylor, Paul M. W. French, R. Mellish, J. F. Solis, L. T. FlorezAbstract:Tunable solid-state lasers, notably the Ti:sapphire laser, have demonstrated the tire ability to generate femtosecond pulses1–4 as short as ~10 fs,3 by exploiting the optical Kerr effect. Amplitude modulation is achieved through self-focussing (Kerr Lens Mode-locking) and the final pulse duration, is determined by the interaction of phase modulation with Intracavity Dispersion. Cr3+:LiSrAlF6, is an attractive alternative to T:sapphire, ± that may be efficiently pumped by laser diodes at 670 nm and by flash-lamps or arc-lamps.
