The directional amplified spontaneous emission (ASE) along the laser tube of an iodine photodissociation laser (IPL) amplifier is measured and the experimental results are compared with the one-dimensional ASE theory. Also, we have measured the loss of the stored energy in the IPL amplifier due to the omnidirectional ASE. The loss is found to be 13.5% for the present amplifier when the laser medium i-C3F7I is 72 Torr and no argon buffer gas is added. But by adding the argon buffer gas to 210 Torr, it is reduced to 4.2%.
