Abstract

In this paper the coupling losses in planar waveguide resonators are calculated and the coupling losses for the EH 11 mode of various planar waveguides are presented as a function of mirror curvature and position. It is shown that there exist two special geometries to provide low coupling losses which is different from the square waveguide. The design and the mode properties of a planar waveguide resonator are discussed.

Abstract

Abstract: Tunable third-harmonic and fourth-harmonic generations of pulsed CO2 laser radiation in a GaSe crystal were demonstrated. The optical properties of GaSe and phase-matching conditions in harmonic generations were investigated. The output peak powers for 3.2μm and 2.4μm were measured to be 1500W and 320W, with corresponding conversion efficiency from 9.6μm of 0.1% and 0.02%, respectively. [Copyright &y& Elsevier]

Abstract

Abstract: Coherent terahertz pulses have been generated at a range of 236.3–1104.5μm (0.27–1.3THz) by one CO2 laser with dual-wavelength output based on collinearly phase-matched different frequency generation (DFG) in a GaSe crystal. This source has the advantages of compact and simplicity for tuning. The output power of the THz pulse and phase-matching conditions were investigated. The maximum single pulse energy of 11nJ was generated at a frequency of 1.23THz (243.6μm), corresponding to a peak output power 182mW. [Copyright &y& Elsevier]
