We have examined the advantages of using Nd3+/YAG as an amplifier for a 6 psec FWHM pulse generated by a mode-locked Nd3+/glass oscillator. The Nd3+/glass oscillator pulse is characterized by 100 cm-1bandwidth at 1060 nm with variable temporal substructure. Passage of this pulse through a Nd3+/YAG rod resulted in wavelength-selected amplification of the specific Nd3+/YAG lines located within the envelope of the Nd/glass pulse. The result is a 100-fold amplified pulse consisting of two bands at 1061 nm and 1064 nm, each <3 cm-1in bandwidth with an average duration of 6 psec and as low as 4 psec.
