Abstract:
The following fluorinated iodides were tested as iodine-laser active media: C4F9J,C5F11J,CF3OCF2CF2J, and C3F7OCF2CF2J. A stimulated emission output energy of 80–85 mJ/cm3 was obtained from perfluorobutyl iodide (without an inert dilutent). This was comparable with the output achieved from n- and iso-perfluoropropyl iodides which are the most efficient active substances for iodine lasers. The lasing quenching mechanism was analyzed theoretically for a C4F9J laser.
