Pulse dynamics in chirped-pulse fiber oscillators - Scaling towards 100 µJ
2009 Edition, June 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this contribution, we report on the investigation of energy scaling in modelocked fiber oscillators based on recent experimental results. Our numerical simulation is done with a non-distributed model, treating every part of the cavity (Fig.1.a) separately by...

Pulse Ring Oscillator Tuning via Pulse Dynamics
2017 Edition, November 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents a practical method for improving timing uncertainty due to thermal noise in a ring oscillator. The methodology utilizes delay elements with non-linear behavior dependent on event separation, the period between successive events. Pulse logic gates are shown...

Pulse dynamics in spatiotemporal mode-locked multimode fiber lasers
2018 Edition, October 1, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We report on the experimental observation of multiple-soliton (harmonic mode-locking, multiple pulses, etc.) and period-timing bifurcations in spatiotemporal mode-locked multimode fiber lasers. The transition of operation states, from uniformity output to period-timing...

Short pulse dynamics in quantum cascade lasers
2012 Edition, December 1, 2012 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Since the first ever demonstration of the quantum cascade lasers (QCLs) in 1994, there has been extensive research on its improvement for various reasons. One of them is to produce ultrashort optical pulses. The nonlinearity in the index of refraction of a lasing medium can be...

We present the measurement results of pulse dynamics in a mode-locked Er3+ fiber laser. The quantitative data will be useful for determining the noise-limits of optical frequency combs generated by mode-locked fiber lasers.

Inter-Pulse Dynamics at High Repetition Rates by Femtosecond Ionization in Gas-Filled Fibres
2019 Edition, June 1, 2019 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Summary form only given. Nonlinear propagation of intense ultrashort laser pulses in gases is mostly understood to be influenced only by the pulse itself, i.e., by single-shot dynamics, because relaxation processes are typically faster than the time between pulses...

Pulse dynamics of all-normal dispersion mode-locked ytterbium lasers
2009 Edition, June 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Spectral filtering in passively mode-locked all-normal dispersion Yb-fiber lasers offers the great potential of realizing cost-effective, compact, alignment free and low-noise all-fiber based systems [1,2]. Besides the filter bandwidth the length of the passive fiber...
