A stable dual-wavelength thulium-doped fiber laser operating at 1.9 μm using a short length of photonic crystal fiber (PCF) has been proposed and demonstrated. The photonics crystal fiber was 10 cm in length and effectively acted as a Mach-Zehnder interferometry element with a free spectral range of 0.2 nm. This dual-wavelength thulium-doped fiber laser(More)
In this paper, the composite nonlinear feedback (CNF) technique is applied for yaw tracking control of active front steering system with the objectives to improve the transient performance of yaw rate response. For lateral and yaw dynamics analysis, nonlinear and linear vehicle models are utilized as actual vehicle plant and for controller design(More)
—Finite element models were developed to virtually carry out laser-micromachining of MEMS components. Four different MEMS components – micro-bridge, micro-cantilever array, micro-mirror and micro-come-were considered in the virtual work. Heat flux propagation and temperature plots generated by virtual laser-micromachining were compared and discussed. The(More)
