“…The first aerosol generator, developed by Blauer and co-workers [49], incorporated a gas-liquid separator. Other efforts which used a separator included those in Russia [50,51], the Czech Republic [52], and Japan [53] (although Japan's separator was gravity). Several of these generator concepts are shown in Figures 7 and 8.…”

Since the initial demonstration of chemical oxygen iodine lasers in 1977, researchers have realized that the heart of the COIL system is the singlet oxygen generator. This drives the performance of the system in terms of output power, mass efficiency, engineering complexity, reliability and maintainability. For this reason the singlet oxygen generator has been the focus of intense research and development efforts over the last 30 years. This paper reports on the history of singlet oxygen generators -starting with the simple sparger design used in the initial COIL demonstration and ending with current jet or droplet generators used in laboratories around the world. The relative performance of the different generator types will naturally lead to performance goals for the research efforts of the future.

The singlet oxygen generator (SOG) is the heart of chemical oxygen iodine laser. A new swirl-jet-type SOG was proposed which consists of a reaction part and a separation part. Planar laser-induced fluorescence combined with maximum entropy method were used to study the droplet size distribution, and a modified Muschelknautz model and Computational Fluid Dynamics were used to simulate the separation efficiency of vapor and liquid phases. The results of the net reaction predict 99.2% conversion of chlorine and 42.2% yield of singlet oxygen, demonstrating the superiority of the new type of SOG.

Improving the chemical efficiency of the supersonic chemical oxygen-iodine laser (COIL) is a key issue for the design of devices for both defense and industrial applications. Efficiencies around 30% for the supersonic COIL have been the state of the art in the last decade. Here, we report the achievement of a record (40%) for the chemical efficiency of the supersonic COIL. More specifically, we show that by carefully studying and optimizing the operation of the chemical generator, the mixing of heavy and light molecules in the gas phase and the optical extraction efficiency, we have approached the theoretical limit for the chemical efficiency.
