Yb-doped bulk materials are becoming an effective technical way for delivering high power ultrashort pulse lasers. They are inexpensive and easy to be processed, adjusted, and resistant to higher pulse energy, all of which make bulk-material-based ultrashort pulse laser amplifier be a hot topic. Usually, there are two kinds of configuration for amplifiers, travelling-wave (single, double-pass, four-pass) amplifiers and regenerative amplifiers. The gain media are not limited to the well-known Yb∶YAG, Yb∶KGW, and Yb∶KGW, such new candidates as Yb∶CALGO, Yb∶CaF₂, Yb∶Lu₂O₃ and Yb∶Y₂O₃ are also emerging. Efforts are paid to review currently reported representative results, to show the potential application of Yb-doped bulk materials as the base for generating ultrashort pulse lasers with average power from hundreds of to thousands of watts.
