33fs Ybfiber laser comb locked to Csatomic clock
(IEEE, 2013)Despite the prevalence of fiber frequency combs around 1.5 μm, few fully stabilized frequency combs have been demonstrated around 1.0 μm, despite the generally superior performance of Ybfiber lasers compared to Erfiber ... 
83 W, 1 ns, 3.1 MHz allfiber laser for micromachining
(IEEE, 2011)Fiber lasers are commonly used for various material processing applications. The advantages (such as simplicity of the system, high material removal rate) and disadvantages (larger heataffected zone, reduced precision) ... 
Allfiber nanosecond laser system generating supercontinuum spectrum for photoacoustic imaging
(IEEE, 2013)Photoacoustic microscopy (PAM) research, as an imaging modality, has shown promising results in imaging angiogenesis and cutaneous malignancies like melanoma, revealing systemic diseases including diabetes, hypertension, ... 
Allfiber Ybdoped laser modelocked by nanotubes
(IEEE, 2013)Singlewall carbon nanotubes (SWNTs) and graphene have emerged as promising saturable absorbers (SAs), due to their broad operation bandwidth and fast recovery times [13]. However, Ybdoped fiber lasers modelocked using ... 
Analytical expressions for the localfield corrections in doublelayer electron systems
(Academic Press, 1999)We develop an extension of the sumrule version of the Singwi, Tosi, Land, and Sjolander (STLS) scheme applied to a doublelayer electron system. We present analytical expressions for the intralayer and interlayer static ... 
Balancing gain narrowing with self phase modulation: 100fs, 800nJ from an allfiberintegrated Yb amplifier
(IEEE, 2013)There is much progress in Ybfiber oscillatoramplifier systems, which enable generation of highrepetitionrate, microjoule energies and subpicosecond pulse widths [1,2]. Given the extremely large total gain factors to ... 
Characteristic equations for the lasing Modes of infinite periodic chain of quantum wires
(IEEE, 200806)In this paper, we study the lasing modes of a periodic open optical resonator. The resonator is an infinite chain of active circular cylindrical quantum wires standing in tree space. Characteristic equations for the ... 
Disorderfree localization around the conduction band edge of crossing and kinked silicon nanowires
(A I P Publishing LLC, 2015)We explore ballistic regime quantum transport characteristics of oxideembedded crossing and kinked silicon nanowires (NWs) within a largescale empirical pseudopotential electronic structure framework, coupled to the ... 
Electrooptic modulation of InAs quantum dot waveguides
(Technische Universiteit Eindhoven, 2008)The linear electrooptic properties in waveguides containing selforganized In As quantum dots were studied experimentally. FabryPerot measurements at 1515 nm on InAs/GaAs quantum dot structures yield a significantly ... 
Mesoscopic Fano effect in an AharonovBohm interferometer Coulombcoupled to a nearby quantum dot
(Wiley, 2007)Motivated by the pionieering experiments of Buks et al. [Nature 391, 871 (1998)] we investigate the visibility of the Fano effect in a singledot AharonovBohm interferometer which is Coulombcoupled to a nearby quantum ... 
Negative refraction and focusing by a lefthanded material slab in free space
(IEEE, 2006)Negative refraction and focusing by a lefthanded metamaterial (LHM) slab are experimentally verified. We measured refractive index of slab as 1.86. The flat lens behavior of LHM is demonstrated for two different point ... 
Nonthermal material and tissue processing with 100 MHz and 500 MHz repetition rate bursts
(IEEE, 2013)There are a number of applications that would avail a pulse pattern in the form of closely grouped and uniformly spaced pulses, i.e., bursts [1]. Closely grouped pulses with pulse to pulse separation in the order of a few ... 
Properties of a microjouleclass fiber oscillator modelocked with a SESAM
(IEEE, 2011)Energy scaling of ultrafast Ybdoped fiber oscillators has experienced rapid progress largely driven by many applications that require high average power femtosecond pulses. The fundamental challenge for ultrafast fiber ...
