The thermodynamics of using laser heating in conjunction with magnetic compression in THETA -pinch plasmas is discussed. It is shown that the minimum laser energy required to achieve a given plasma filling factor LAMBDA (ratio of plasma to plasma tube area), is E/sub laser/= LAMBDA /sup 2/3/E/sub plasma/ and that any flliing factor up to LAMBDA = l can be achie ved. The proposed schemes have important implications for either increasing the performance of standard THETA pinches or for replacing the single-turn THETA -pinch coil by a multitum solenoid. (auth)
