摘要：

Ultrashort　pulses　were　generated　in　passively　mode-locked　Nd:YAG　and　Nd:GdVO4　lasers　pumped　by　a　pulsed　laser　diode　with　10-Hz　repetition　rate.　Stable　mode-locked　pulse　trains　were　produced　with　the　pulse　width　of　10　ps.　The　evolution　of　the　mode-locked　pulse　was　observed　in　the　experiment　and　was　discussed　in　detail.　Comparing　the　pulse　evolutions　of　Nd:YAG　and　Nd:GdVO4　lasers,　we　found　that　the　buildup　time　of　the　steady-state　mode-locking　with　semiconductor　saturable　absorber　mirrors　(SESAMs)　was　relevant　to　the　upper-state　lifetime　and　the　emission　cross-section　of　the　gain　medium.
