Abstract:
A comprehensive analytical model for optimization longitudinal pumping of ideal 4-level lasers is presented for accurate analysis by removing limiting assumptions on active length and pump beam radius in the gain medium. By taking into account the circular-symmetric Gaussian pump beam including the M² factor, an analytical formula for the root mean square of the pump beam in the active medium is developed to relate properties of the gain medium and pump beam to the requirement on efficient optimum design. Under the condition of minimum root mean square of pump beam radius inside the active medium, the key parameters of the optimum optical coupling system have been analytically derived. Using these parameters, optimum mode size and maximum output efficiency are derived as a function of the gain medium length, absorption coefficient, pump beam M² factor and input power. Dependence of the obtained parameters on the gain medium length, absorption coefficient, pump beam M² factor and input power has been investigated. The results of this theory are found to be more comprehensive than the previous theoretical investigations. The present model provides a straightforward procedure to design the optimum laser resonator and the coupling optics for maximizing the output.

Abstract:

There is no polyeric detector used to register the beam profile of UV lasers. Here a method is proposed for the measurement of intensive UV beam pattern of the excimer lasers based on the photoablated polycarbonate detector after coherent UV exposure and the subsequent electrochemical etching. UV laser induced defects in the form of self microstructuring on polycarbonate are developed to replcate the spatial intensity distribution as a beam profiler.

7.4 L. Mashhadi, Gh. R. Shayeganrad, “Physical Investigation of Sparking of metals Within Microwave Oven”, Amikabir Journal of Science & Technology, 68, 2008.

Abstract:
Up to now, some microwave oven experiments have been done by placing non-food objects such as metal objects, CDs, lightbulbs in the microwave oven cavity [1-4]. It is well understood, when a metal object is placed inside the oven cavity, sparking will result. In this paper, we have theoretically and experimentally investigated the basis of the physical process of spark of metal objects within the microwave oven cavity, based on the electrostatic and alternating field. Considering cavity Q-factor, the resonant modes characteristics of both TE and TM electromagnetic fields in the oven cavity are determined. Theoretical equations for electric field components around the metal disks and sharp edges, or conical points, as well as surface-charge density are obtained by solving Laplace equation in polar and elliptical coordinates. The equations have been investigated with experimental results by CD-ROMs and several types and shapes of metal ring and wire at atmospheric pressure, room temperature and normal humidity condition. Experimental results show a good agreement with the theoretical predictions.

(2009), 420-433.

Abstract:
Radioactive pollutants which are released into the atmosphere are known to present a hazard to human health; therefore they must be identified and well protected. Here, an improved remote sensing system is investigated for monitoring radioactive plumes released into the atmosphere from nuclear sites. It is based on the combination of DIAL technique with a phoswich detector array. The DIAL, using a tunable UV/Vis laser, measures the concentration of the radionuclide and the plume distance, whereas the phoswich detects characteristic hard X/γ ray emissions. Here, we have shown the ability of a hybrid system for the prompt identification and quantification of the effluents containing the uranium radionuclide, using the parameters of uranium such as absorption cross-section, absorption spectrum and density.

Abstract:

Spatial intensity distribution is one of the fundamental parameters that indicate how a laser beam behaves in an application. Laser printing, material Processing, optical data storage, laser pumping and photochemistry are some of the applications whose efficiency depends on the laser spatial profile and the corresponding beam width. Several electronic methods are currently used to determine beam profiles which includes scanning slit devices, scanning knife-edge profilers and CCD camera imaging systems.

Here, inexpensive, simple and precise technique is presented to record the beam pattern of intensive KrF and ArF excimer lasers on polycarbonate (PC) detectors. An electrochemical etching (ECE) chamber is used to develop the nanoscale latent damages due to photoablation on PC. Previously, we have shown in high dose excimer laser induced microstructure pattern in PC that can be etched and counted.

Russian model excimer laser 1812 KrF and that of flat beam Lambda Physik, LPX 100 are compared. The Lambda Physik LPX owns a flat beam pattern whereas Russian excimer laser having a nearly Gaussian spatial intensity. The measured profiles are in good agreement with Pyrocam profiler. The significant advantage of this technique, is to determine the real beam pattern of intensive excimer lasers without distortion due to beam attenuation effects.

Abstract:

SF₆ with high dielectic strength is used in sealed HV installation to compact the electrical distribution sites. Therefore, the SF6 leakage sensing has the environmental and economical significantce. Here, we have quatitatively shown that DIAL using a pair of pulsed CO₂ lasers enables us to detect SF₆ effluent in ppm level at relatively longer distances respect to competitive CW laser based BAGI and passive IMSS systems. Moreover, investigation temporal distribution of SF₆ emission from DIAL response indicates that heavy SF₆ molecules are reluctant to diffuse fast, willing to accumulate over the ground at definite locations.

8.21 G. Shayeganrad, "Remote leak monitoring of gaseous uranium hexafluoride by UV-DIAL", Proceeding of SPIE, Vol. 7462-19, 2-6 August (2009), San Diego, California, USA.

Abstract:

Uranium hexafluoride (UF₆) molecule is highly toxic and finding leaks into the atmosphere has environmental and health significant. A differential absorption lidar (DIAL) system for concentration monitoring of UF₆leaked into the atmosphere is being developed. This paper describes a new UV-DIAL long range remote sensor for quick identification and spatial distribution monitoring as well as measuring concentration and allows seeing where gas exits are located, what may be possible for UF₆ detecting leaks and repair them. The system uses a frequency-quadrupled Nd:YAG laser for the on wavelength and a Nd:YAG-pumped Coumarin dye laser with Lithman setup operating in the frequency doubled mode for the off wavelength. We synchronously pumped a Coumarin dye laser with the 532-nm light from the diode-pumped Nd:YAG system to achieve tunable light around 245 nm. By mapping the UF₆ distribution concentration over an area, the leakage location can be determined due to UF₆ absorption at 245 nm. This is particularly true in UF₆ leak detection applications such as UF₆- storage container and UF₆-pipeline. The systematic errors due to aerosol extinction and absorption by atmospheric constituents are considered. It has been found that the systematic errors in remote sensing of UF₆at 266 nm and 245 nm can be negligible.
