Abstract

The feasibility of a 100 kJ class chemically pumped iodine laser amplifier is studied by numerical calculations of the Maxwell-Bloch equations. The idea is based on a chemical iodine pulse laser utilizing a porous-pipe, high-pressure singlet oxygen generator. It is shown that at the high singlet oxygen pressure conditions, the energy transfer reaction from singlet oxygen to ground state iodine atom directly deposits energy on the pulse amplified. Therefore, it is possible to operate an amplifier with low iodine concentration, which ensures the slow deactivation of the stored energy sufficient to fill up a cell of 80 cm in diameter.
