The article mainly discusses the design of pump coupling system that is one of the key technology of disk laser. In the optical system, we applied three fast and slow axis collimation cylinder lenses and one cylinder HR mirror. The fast and slow collimation cylinder lenses collimate 220-bar diode lasers stack's pump light. The cylinder HR mirror insure the pump laser 4 times pass through the laser medium. The beam size at the pumped area is 23 mm×27 mm. The coupling efficiency is 85%. The pumping light beam tested by CCD camera is nearly symmetric.
