    We present an efficient zero-phonon-line pumped cryogenic Yb:YAG laser passively Q-switched by Cr:YAG with different initial transmissions. At 140K, with 85% initial transmission of Cr:YAG, a maximum average output power of 5.19 W with a repetition rate of 24.7 kHz was achieved leading to a slope efficiency of 55.7%. The maximum pulse energy, minimum pulse width and peak output power obtained in this case were 0.21 mJ, 142 ns and 1.48 kW respectively.
