摘要：

In　this　paper,　the　mechanism　of　mode-locking　using　a　semiconductor　saturable　absorption　mirror　(SESAM)　in　solid　laser　was　analyzed.　We　proposed　a　new　opinion　about　how　the　SESAM　works　to　realize　mode-locking.　Because　the　special　structure　of　SESAM,　when　it　works　in　a　mode　locking　laser,　SESAM　is　not　just　an　absorber　but　also　works　as　a　gain　medium　together　with　solid　crystal.　In　oscillator　cavity,　solid　medium　is　pumped　by　an　outside　pump　source　(such　as　a　semiconductor　laser)　and　a　light　field　Ec　is　produced.　This　light　field　Ec　works　as　a　pump　source　and　pumps　SESAM　to　produce　another　light　field　ES.　And　then　solid　gain　medium　works　as　an　amplifier.　When　gain　and　loss　keep　balance　in　cavity,　continuous　wave　mode-locking　(CWML)　is　realized.
