Repetition rate tuning enables the fast acquisition of THz pulse profiles [1]. By using this method we demonstrate a compact and broadband terahertz time domain spectroscopy system (THz TDS) driven by ytterbium doped fiber laser source. The importance of this method is realized in that Yb: doped fiber lasers can be amplified to sub-millijoule pulse strengths more easily than other types of fiber lasers [2]. Hence, it has the potential to be used in excite-THz probe experiments. Furthermore, the repetition rate-tuning adds flexibility in the excite-probe techniques. These attributes as well as THz generation and detection are investigated with the laser that was developed.

Fiber-integrated terahertz spectrometer driven by ultrafast ytterbium doped fiber laser
Keskin, Hakan; Altan, Hakan; Berberoğlu, Halil Giray; Department of Physics (2013)
In this thesis, development of a Terahertz time domain spectrometer (THz-TDS) driven by an ultrafast Ytterbium (Yb) doped ber laser, whose repetition rate can be tuned, was investigated to show that it can be used in Optical Sampling by Cavity Tuning (OSCAT) technique which enables the fast acquisition of THz pulse pro les. Central wavelength of the Yb-doped laser developed for this study is 1031 nm. The output average power was measured to be 90 mW which corresponds to about two nanojoule per pulse at 51 ...
Approximate Bayesian Smoothing with Unknown Process and Measurement Noise Covariances
Ardeshiri, Tohid; Özkan, Emre; Orguner, Umut; Gustafsson, Fredrik (2015-12-01)
We present an adaptive smoother for linear state-space models with unknown process and measurement noise covariances. The proposed method utilizes the variational Bayes technique to perform approximate inference. The resulting smoother is computationally efficient, easy to implement, and can be applied to high dimensional linear systems. The performance of the algorithm is illustrated on a target tracking example.
Open problems in CEM: A new look at the stability analysis of the finite-difference time-domain method
Ergül, Özgür Salih; Özakın, M. Burak (2014-01-01)
The stability analysis of a numerical time-domain method plays a crucial role in well understanding the numerical behavior of the algorithm. The stability analysis should therefore be investigated in all senses. In this work, a new look at the stability analysis of the Finite-Difference Time-Domain Method is given. A novel link is constructed between the numerical-dispersion analysis and the stability analysis by using the sampled values of the unit space and time steps. Unification of these two analyses th...
Cascaded Multilevel Inverters Fault Control
Farzaneh, Alireza; Nazarzadeh, Jalal (2011-09-10)
This paper proposes a new control method to increase cascaded multilevel inverters (CMI) efficiency at faulty condition. The influence of most probability fault on CMI with carrier based pulse width modulation (CBPWM) is investigated and the maximum output voltage is derived without elimination of faulty power cell. This method is able to produce balanced phase voltage on faulty phase. In addition proposed method can be used in the H -bridge cascaded multilevel inverter of any voltage levels. Simulation res...
Wavefront-ray grid FDTD algorithm
Ciydem, Mehmet; Koç, Seyit Sencer (2016-01-01)
A finite difference time domain algorithm on a wavefront-ray grid (WRG-FDTD) is proposed in this study to reduce numerical dispersion of conventional FDTD methods. A FDTD algorithm conforming to a wavefront-ray grid can be useful to take into account anisotropy effects of numerical grids since it features directional energy flow along the rays. An explicit and second-order accurate WRG-FDTD algorithm is provided in generalized curvilinear coordinates for an inhomogeneous isotropic medium. Numerical simulati...
