We present the design and experimental results for the flashlamp‐pumped Ti:Sapphire laser system used at the Stanford Linear Accelerator Center (SLAC). This laser system is used in conjunction with the Polarized Electron Source to generate polarized electron beams for fixed target experiments (e.g. the E‐158 experiment). The unique capabilities such as high pulse‐to‐pulse stability, long pulse length and high repetition rate is discussed. Emphasis is placed on recent modifications of the laser system, which allow ultra‐stable operation with 0.5&percent; rms intensity jitter. © 2003 American Institute of Physics
