To fully utilize the broad linewidth of Nd:glass and overcome its problems in mode locking, we used two laser media, i.e. Nd:LiYF/sub 4/ and Nd:glass, in a single cavity to form a hybrid Nd laser for mode locking. Yan et al. in Appl. Phys. Lett., vol. 67, p. 3679, 1995, demonstrated continuous wave (cw) operation of the hybrid Nd laser and showed that it can lase with a spectrum characteristic of Nd:YLF, while most of the gain is from Nd:glass. This indicates that the complementary and good properties of Nd:glass and Nd:YLF can be utilized in the hybrid Nd laser for ultrashort pulse generation. In this paper we report the first demonstration of active mode locking of the hybrid Nd laser.
