Abstract
The ground state oxygen and water vapor are important species in chemical oxygen-iodine laser. The detectivity required in the chemical oxygen-iodine laser device is about 0.03 Torr for both $H_{2}O$ and $O_{2}$(X). We have shown that these parameters and the temperature of chemical oxygen-iodine laser medium can be measured by intracavity laser spectroscopy based on simple standing wave Ti:sapphire laser. Using 120-$s$ laser generation time, we have demonstrated the detection sensitivities to be 6.10$\pm$14 and 3.10$\pm$$14 cm^{-3}$ for $H_{2}O$ and $O_{2}$(X), respectively. The oxygen concentration measurement error does not exceed 5% in the range 2.10$\pm$15-10$\pm$$16 cm^{-3}$. The temperature measurement error does not exceed 25K in the range 200-500K.
