High power lasers typically form a multidisciplinary technological area laced with innumerable challenges in its realization as a practical system. The prime amongst them are infrared gas laser sources such as Carbon-di-Oxide Gas Dynamic Laser, Hydrogen Fluoride, Deuterium Fluoride Laser and Chemical Oxygen Iodine Laser etc. Each of these laser systems is associated with a unique as well as complex active medium environment involving intense interaction between lasing and pumping species under specific gas dynamic conditions. The parameters viz. specie concentration of the lasing, pumping mediums and other by-products, medium homogeneity, individual constituent gas flow rate, pressure and temperature at critical locations and cavity Mach number are very crucial in determining the output of the gas laser system. It is essential to determine these parameters non-intrusively, with necessary precision so as to optimize these lasers especially in case of largescale systems. Thus, the focus of this paper is to review and discuss the existing applicable optical detection methodologies ranging from the more established methods such as optical absorption/emission spectroscopy to very contemporary like Raman spectroscopy, cavity ring down spectroscopy, laser induced fluorescence/ planer laser induced fluorescence etc., which are relevant for the diagnostic needs of gas lasers.

Over the last decade new advanced gas lasers have emerged as possible candidates for high power laser systems that may supplant more conventional chemical and gas laser systems. Among these are the electric oxygen-iodine laser (ElectricOIL), the diode pumped alkali laser (DPAL), the exciplex pumped alkali laser (XPAL), and the optically pumped metastable rare gas laser. In this paper we will primarily focus on the ElectricOIL and XPAL systems, and discuss some of the recent experiments and modeling of these systems.

A chemical oxygen-iodine laser (COIL) is an electronic transition, low pressure, high throughput system. The use of this laser demands a suitable pressure recovery system. This paper proposed a novel pressure recovery system based on chemical absorption and the feasibility for COIL with CO 2 as buffer gas (CO 2 -COIL) was investigated. The novel pressure recovery system works by chemisorbing the CO 2 -COIL effluents into two fixed-beds maintained at initial temperature of around 293-323K. Compared with the cryosorption system for N 2 -COIL based on physical absorption, the novel chemisorptions based pressure recovery system has a simpler logistics and a shorter run-to-run preparation time.Two kinds of solid chemo-sorbents were designed and synthesized. One was used for chemisorbing the oxidizing gases such as O 2 ,Cl 2 and I 2 , another was used for chemisorbing the acidic gas such as CO 2 . The capacities of the two sorbents were measured to be 3.12 mmol(O 2 )/g and 3.84 mmol (CO 2 ) /g, respectively. It indicated that the synthesized sorbents could effectively chemosorb the CO 2 -COIL effluents. Secondly, analog test equipment was set up and used to study the feasibility of the novel pressure recovery system used for CO 2 -COIL. The test results showed that the novel pressure recovery system could maintain the pressure under 6 Torr for tens seconds under the continuous gas flow. It showed that the novel pressure recovery system for CO 2 -COIL based on chemical absorption is feasible.
