Modern solitons fiber lasers systems sought for imaging, micromachining, metrology, spectroscopy, and sensing applications, require multifunctional light sources with fully controlled switching features to avail the necessary optical signal. Existing single cavity laser have limitations on generation of multistate due intrinsic dispersion, nonlinearity, filtering, gain, loss. Herein, very first...

One way to improve the productivity of knowledge workers is to increase their self-awareness about productivity at work through self-monitoring. Yet, little is known about expectations of, the experience with, and the impact of self-monitoring in the workplace. To address this gap, we studied software developers, as one community of knowledge workers. We used an iterative, user-feedbackdriven d...

Background: Although compliance with all self-care behaviors is necessary for successful management of diabetes, patients with diabetes often refuse favorable self-care. This article is aimed to test the effects of a theory-related intervention to conduce self-aid adherence and metabolic curb in patients having type-2 diabetes.  Methods: In this randomized controlled trial, 80 patients su...

We report a self-starting passively mode-locked soliton source generating 1-ps-wide pulses. The laser is configured as a ring with an erbium-doped fiber gain medium, a length of conventional fiber that provides the required dispersion and Kerr nonlinearity, and an intracavity multiple-quantum-well optical amplifier that serves as a saturable absorber and pulse stabilizer. The laser exhibits low...

It has been recently understood that mode locking of lasers has the signification of a thermodynamic phase transition in a system of many interacting light modes subject to noise. In the same framework, self starting of passive mode locking has the thermodynamic significance of a noise-activated escape process across an entropic barrier. Here we present the first dynamical study of the light mo...

We describe a diode-pumped Kerr-lens mode-locked Cr(3+):LiSrAlF(6) laser that produces 50 mW of 70-fs pulses in the 820-890-nm range when pumped by two red diodes of 400 mW each. By using a lower-transmission output coupler we have demonstrated for the first time to our knowledge a self-starting regime with an output power of 10 mW and 55-fs pulses.
