Dynamics of passive harmonic mode-locking
Nonlinear Photonics, 2007A comprehensive theoretical model of harmonic mode-locking is presented in which the nonlinear mode-coupling behavior in a waveguide array is used to achieve stable and robust passive mode-locking.

Harmonic mode locking of the Nd:YAG laser
IEEE Journal of Quantum Electronics, 1972We present experimental and theoretical results for N th harmonic mode locking of a Nd:YAG laser with an intracavity phase modulator operating at N = 2, 3, 4, and 5 times the fundamental c/2L frequency. The bandwidths of the resulting mode-locked spectra depend upon modulation frequency, modulation depth, and laser cavity losses in good agreement with ...

Sb4O5Cl2 for 34th-order-harmonic mode locking
Optical Materials, 2020Abstract Due to the excellent electrochemical characteristics, Sb4O5Cl2 has been potentially used in flame retardant, catalyst, and anode materials, etc. At the same time, it has broad application prospects in optics and optoelectronics because of its strong inoxidizability, high damage threshold and relatively high-photoelectric conversion ...

Harmonic mode locking in a sliding-frequency fiber laser
Optics Letters, 2011We demonstrate a sliding-frequency mode-locked (SFM) erbium fiber laser generating 20 ps pulses with center wavelengths rapidly sweeping across a spectral range of 50 nm. Excess optical nonlinearity in the laser cavity leads to multipulsing, with a tendency to tight pulse bunching (

Pulse Formation, Harmonic Mode-Locking, and Stability in Actively Mode-Locked Laser Cavities
IEEE Journal of Quantum Electronics, 2009Theory and simulations of the mode-locking dynamics in an active cavity driven by an acoustooptic modulator is considered. Three solution types and their stability are considered: plane-waves, solitons, and periodic pulse trains. By tuning the gain pumping in the cavity, all three solution types are exhibited with the transition in stability between ...

Timing inequality in rational harmonic mode-locking
Conference on Lasers and Electro-Optics (CLEO 2000). Technical Digest. Postconference Edition. TOPS Vol.39 (IEEE Cat. No.00CH37088), 2000Summary form only given. Rational harmonic mode-locking (RHML) has attracted wide consideration in fiber lasers in recent years, because this technique provides a possibility for ultrahigh-repetition-rate pulse generation from a low frequency driving signal. A potential usage of the RHML has also been proposed in an optical pulse storage.

Stabilizing Harmonically Mode-Locked Fiber Laser
2007 IEEE International Conference on Signal Processing and Communications, 2007Applications of ultra short pulses in optical signal processing, communications and high speed electronics have grown rapidly in recent years. However, high stability of the generated pulses is of prime importance for these applications. This paper describes the quantitative stability analysis of optical pulses generated through passively mode locked ...

PbSe Nanosheets for HighâPerformance Harmonic Mode Locking
Annalen der Physik, 2022AbstractAs a new emerging semiconductor with interlayer bandgap, lead selenide (PbSe) have broad prospects in the fields of electrocatalysis, photocatalysis, infrared optoelectronic devices, optoelectronics, and ultrafast photonics. Among them, ultrafast photonics is receiving a lot of attention due to its ultrashort pulse, strong peak power, narrow ...

Cladding-pumped passive harmonically mode-locked fiber laser
Optics Letters, 1996A passive harmonically mode-locked fiber laser cladding pumped by a broad-area diode-laser array is described. Harmonic mode locking is obtained in a frequency range from 33.3 to 128.6 MHz, where the higher frequency limit is imposed because of insufficient available pump power.

Dispersion management in a harmonically mode-locked fiber soliton laser
Optics Letters, 2000Harmonically mode-locked Er-fiber soliton lasers have become a reliable source of high-repetition-rate picosecond pulses in high-speed communications and photonic analog-to-digital conversion systems because of their low-noise, dropout-free operation.
