The output properties of an extracavity PbWO4 Raman laser are investigated. A PbWO4 solid Raman amplifier is also presented. The extracavity PbWO4 Raman laser and PbWO4 solid Raman amplifier are both pumped by an electro-optically Q-switched Nd:YAG laser. For the extra cavity PbWO4 Raman laser, with incident pulse energy of 40 mJ, the obtained maximum conversion efficiency of the first Stokes is 13%. When the pump energy is 48 mJ, the obtained maximum pulse energy and conversion efficiency of the second Stokes are 11 mJ and 23%, and the conversion efficiency of the full scattering laser is 34%. For the PbWO4 solid Raman amplifier, the maximum output energy of the amplifying first Stokes pulse and the amplification factor are 11 mJ and 3.3.
