Small 5-mm-diam high-density 3 x 10/sup 17/ cm/sup -3/ theta-pinch plasma columns 1-m long have been heated by intense long-wavelength laser radiation (10 ..mu..) along their entire length. Refractive beam trapping has been achieved when laser heating begins during or before the theta-pinch implosion. Plasma temperatures have been increased from under 2 eV to maximum values of between 30 and 90 eV, in agreement with a MHD laser heating code.
