Ultrahigh harmonics (up to 50-60) of the seed wave from an external sub-piccosecond terawatt laser are shown to be generated with a reasonable intensity. A small number of side-bands are shown to be present simultaneously with the central line. The central line intensity appears to be tolerant to the laser power fluctuations up to 10-15%.}, year = {1997}, journal = {Nuclear Instruments & Methods in Physics Research Section a-Accelerators Spectrometers Detectors and Associated Equipment}, volume = {393}, number = {1-3}, pages = {348-351}, month = {Jul 1}, isbn = {0168-9002}, doi = {10.1016/s0168-9002(97)00508-1}, language = {eng}, }
