Abstract
Chemical oxygen iodine laser, or COIL, is an impressive type of chemical laser and is widely adopted in the past several decades. A novel approach for obtaining high power vortex beam is explored. A seed vortex beam is amplified by a chemical oxygen iodine amplifier. Numerical simulation is carried out to confirm the feasibility of obtaining high power vortex beam based on chemical oxygen iodine amplifiers. The behavior of the vortex beam is also revealed. As the beam is modulated by the gain media, the beam profile gets asymmetric, and the vortex center no longer locates at the midpoint between the upstream and downstream intensity maximum points. This study suggests a potential approach for developing chemical oxygen iodine lasers.
