Numerous studies have examined the potential impacts of urban expansion on vegetation growth. However, the impacts of urbanization on vegetation growth (Urbi) across urban-rural gradients and its driving forces remain poorly understood. In this study

In most coherent imaging modality, speckle noise is a major cause that blurs the boundary of tissues and degrades the image contrast. By utilizing the unique properties of supercontinuum (SC) generated by noise-like pulses (NLPs) and a simple multi-f

This article presents an experimental and theoretical study of the generation of picosecond bursts by a non-polarization-maintaining ytterbium-doped fiber master oscillator fiber amplifier system. The peak power and pulse energy of the burst are high

We describe generation and amplification of mediumand high-energy noise-like pulses (NLPs) using Yb-doped optical fibers. We also demonstrate supercontinuum (SC) genera‐ tion techniques in which NLPs serve as the pump. SC pumped by NLPs has been em

We report the performance of a picosecond master-oscillator power amplifier (MOPA) system based on a diode-pumped solid-state (DPSS) seed laser and Yb-doped fiber amplifier. An average power of 28 W at ∼200 MHz repetition rate is achieved by using

We show experimentally and theoretically that the spectral profile of the seed pulse of an Yb-doped fibre-based chirped pulse amplifier (CPA) plays a dominant role for achieving an ultrashort compressed pulse. The picosecond seed pulse from an all-no

A supercontinuum with over 420-nm of spectral bandwidth is generated in a single-modefiber pumped by noise-like-pulses from an Yb-doped fiber laser. The supercontinuum source is successfully employed in a spectral-domain optical coherence tomography

In this chapter, we first considered practical aspects in design and construction of relatively high-average-power picosecond Yb-doped fiber laser systems. Employing a highly stable diode-pumped solid-state laser as the seed source together with prop

We report generation of broadband supercontinuum (SC) by noise-like pulses (NLPs) with a central wavelength of 1070 nm propagating through a long piece of standard single-mode fibers (~100 meters) in normal dispersion region far from the zero-dispers
