Zeziphi izinto ezichaphazelaubude be-laser?

Ubude bobude be-ilezaayimiselwanga yinto enye, kodwa imiselwa ngokudibeneyo yindlela esebenza ngayo indalo (imitha evuselelweyo) kunye noyilo oluthile lwesakhiwo. Isiseko sixhomekeke kwisakhiwo samandla sento esebenzayo, kwaye sincediswa kwaye silawulwa zizinto ezifana nomgodi ojikelezayo kunye nendlela yokumpompa.

Ezi zinto zilandelayo zinokuchaphazela ubude be-laser:

Iilaser zisekelwe kwiindidi ezahlukeneyo ze-laser media, ezifana neegesi, izinto eziqinileyo, ii-semiconductors okanye iifayibha ze-optical ezifakwe i-doped. Isixhobo ngasinye selaser sineempawu ezizodwa, ezinokuchaphazela ubude bayo bokukhanya obunokwenzeka.

2. I-gain medium sisithako esisebenzayo esivelisa imitha evuselelweyo ngaphakathiinkqubo yelaserIimpawu ze-gain medium (ezifana namanqanaba amandla, utshintsho lwe-elektroniki kunye nezikhewu zebhendi) zimisela uluhlu lwamaza olunokwandiswa.

3. Umsebenzi womthombo wepompo kukubonelela ngamandla okuqala kwi-gain medium ukuqalisa inkqubo yokuvelisa i-laser. Ububanzi bomsinga womthombo wepompo buya kuchaphazela imeko yokuvuselela kunye nenqanaba lamandla le-gain medium, ngaloo ndlela ibe nefuthe kubude bomsinga wokukhupha.

4. Ezinye iilaser zixhotyiswe ngeendlela zokulungisa ezinokulungisa ubude be-output, ngaloo ndlela zitshintsha ubude be-emission ngaphakathi koluhlu oluthile.

5. Uyilo lwe-laser resonator (kuquka izibuko kunye nezinye izinto ezibonakalayo) luya kuchaphazela ukukhethwa kobude be-wavelength ngokutshintsha imo ye-resonance kunye neemeko zokuphazamiseka kwesigaba.

6. Iziphumo ze-optical ezingezizo ezilandelelanayo (ezifana nokuphindaphindwa kwe-frequency, ukuvelisa i-sum okanye umahluko, kunye neenkqubo ze-parametric) zinokuvelisa ii-harmonics okanye zivelise ii-wavelengths ezintsha ezingenakuveliswa ngqo yi-laser medium.

7. Izinto ezifana nobushushu kunye noxinzelelo nazo zinokuchaphazelaubude be-laser, nto leyo ebonakala ngakumbi kwiileyiza zegesi. Isiphumo sobushushu kwi-gain medium sinokubangela utshintsho kwi-emission wavelength.

Ngamafutshane, "ukumisela uluhlu lwezinto ezisebenzayo, ukumisela amaxabiso athile kwi-resonant cavity, kunye nokuqinisekisa ukuphuma phantsi kweemeko zokuvuthela" kunye nokumisela ubude bomphumo wokugqibela we-laser.
