I-Laser dynamics ibhekisa ekuveleni kwezixa ezithile zelases ekuhambeni kwexesha, njengamandla okubona kunye nokuzuza.

Ukuziphatha okuguquguqukayo kwe-laser kunqunywe yintsebenziswano phakathi kwendawo ye-optical kwi-cavity kunye ne-medium gain. Ngokubanzi, amandla e-laser aya kwahluka kunye nomahluko phakathi kwenzuzo kunye ne-resonant cavity, kwaye izinga lokutshintsha kwenzuzo limiselwa yinkqubo yokukhutshwa okukhuthazwayo kunye nokukhutshwa okuzenzekelayo (kusenokumiselwa yimpembelelo yokucima kunye inkqubo yokudlulisa amandla).

Kusetyenziswa uqikelelo oluthile. Ngokomzekelo, inzuzo ye-laser ayikho phezulu kakhulu. Kwi-laser yokukhanya eqhubekayo, ubudlelwane phakathi kwamandla e-laser P kunye ne-coefficient yokuzuza g kumngxuma yanelisa le equation yomahluko wokudibanisa ilandelayo:

Apho T_R lixesha elifunekayo kuhambo olunye lokuya nokubuya emngxunyeni, l kukulahleka komngxuma, g_ss luphawu oluncinci lwenzuzo (kwimpompo enikiweyo yokuqina), τ_g lixesha lokuphumla lokufumana (lidla ngokusondela kubomi bamandla aphezulu), kunye E_sat yi twahlutha amandla okufunxa kwi- gain medium.

Kwii-laser eziqhubekayo zamaza, ezona ntshukumo zichaphazelekayo kukutshintsha kokuziphatha kwelaser (ngokuqhelekileyo kubandakanywa ukubunjwa kwe-spikes yamandla ephumayo) kunye nemeko yokusebenza xa kukho ukuphazamiseka kwinkqubo yokusebenza (ngokuqhelekileyo i-oscillation yokuphumla). Kwezi nkalo, iintlobo ezahlukeneyo zeelaser zineendlela zokuziphatha ezahluke kakhulu.

Umzekelo, iilaser ze-doped insulator ziqhelekile kwi-spikes kunye ne-relaxation oscillations, kodwa i-laser diodes ayinjalo. Kwi-laser ye-Q-switched, ukuziphatha okuguquguqukayo kubaluleke kakhulu, apho amandla agcinwe kwindawo yokuzuza aya kutshintsha kakhulu xa i-pulse ikhutshwa. I-Q-switched fiber lasers ihlala ineenzuzo eziphezulu kakhulu, kwaye kukho ezinye izinto eziguqukayo. Ngokuqhelekileyo kubangela ukuba i-pulse ibe nezakhiwo ezincinci kwi-domain yexesha, ezinokuthi ayicaciswanga yile nxaki ingentla.

Inxaki efanayo isenokusetyenziswa kwiilaser ezitshixwayo kwimowudi yokwenziwa; emva koko i-equation yokuqala idinga ukongeza ixesha elongezelelweyo ukuchaza ukulahlekelwa kwe-absorber saturable. Isiphumo sesi siphumo kukuba ukuthotywa kwe-oscillation yokuphumla kuyancipha. Inkqubo ye-oscillation yokuphumla ayithobeki, ke isisombululo esizinzileyo asisazinzi, kwaye i-laser iye yazinza.abanye ukungazinzi ye Q-utshintshe imo-locking okanye ezinye iintlobo ze-Q-switchnge.
