Several potential issues concerning laser-beam propagation thorough the LIFE target chambers are addressed. It is found that the absorption due to inverse Bremsstrahlung limits the gas density to approximately 2 [micro]g/cc of xenon gas. This value is within the gas density estimated to be required to keep the first wall heating to an acceptable level.
