The results of experimental studies of the X-ray lasing on the 3p-3s transitions of neon-like titanium ions are presented. The laser radiation at 1.054 {mu}m was focused to a {approx}30-{mu}m wide line of length from 2 to 8 mm. Plane polished titanium plates were successively irradiated by two pulses: a 400-ps prepulse and a 4-ps main pump pulse delayed by 1.5 ns relative to the prepulse. The total laser energy was 8-10 J. The nanosecond-to-picosecond pulse energy ratio was maintained constant and was equal to 1:3. For a short target length (from 2 to 4 mm), the 326-A line intensity was experimentally observed to grow exponentially with length. The small-signal gain for the X-ray laser radiation is estimated at approximately 30 cm{sup -1}. The X-ray laser beam divergence was equal to about 9 mrad. (lasers)
