For the past five years, strained GaAs photocathodes have been used for the SLAC polarized electron source producing electron beams having a spin polarization of 78% (85%) for high (low) current operation. Photocathode research has been continuously conducted to understand the cathode characteristics and to improve performances. This paper describes the recent developments in the strained photocathode research at SLAC.
