Pulse Amandla Lasers

Amandla okushaya kwe-laser asho amandla adluliswa yi-laser pulse ngeyunithi yesikhathi. Ngokuvamile, ama-laser angakhipha amagagasi aqhubekayo (CW) noma amagagasi ashaya ngamandla, kanti lokhu kwakamuva kubaluleke kakhulu ezinhlelweni eziningi ezinjengokucubungula izinto ezibonakalayo, ukuzwa okukude, okokusebenza kwezokwelapha, kanye nocwaningo lwesayensi. Ukuqonda izici ze-laser pulse energy kubalulekile ekuthuthukiseni ukusebenza kwayo kanye nokwenza ngcono ukusebenza kahle kohlelo lokusebenza.

1. Incazelo kanye Nesikali Sokudonsa Amandla

I-Laser pulse energy ingamandla akhishwa yi-laser pulse ngayinye, ngokuvamile elinganiswa ngama-joules (J). Ngokungafani nama-laser we-wave continuous wave (CW), ama-laser ashaywayo akhulula amandla ngesikhathi esifushane, futhi ubukhulu bamandla ngokuvamile buhlobene nobude besikhathi sokushaya kwenhliziyo (ububanzi bokushaya kwenhliziyo) namandla aphezulu.

Amandla okushaya kwenhliziyo angabalwa kusetshenziswa ifomula elandelayo: E = Ppeak × τ. Lapho u-E engamandla okushaya kwenhliziyo (ama-joule), i-Ppeak ingamandla aphakeme we-pulse (watts), futhi τ ubude besikhathi sokushaya kwenhliziyo (amasekhondi). Lokhu kusho ukuthi amandla okushaya kwenhliziyo ahlobene ngokuqondile namandla aphezulu kanye nobubanzi bokushaya kwenhliziyo.

2. Izici Ezithinta I-Pulse Energy

Kunezici ezimbalwa ezithonya amandla okushaya kwe-laser, okuhlanganisa:

①I-Laser Design kanye nohlobo:
Izinhlobo ezahlukene zamalaser zithinta usayizi wamandla okushaya kwenhliziyo. Isibonelo, ama-laser e-solid-state ngokuvamile anikeza amandla aphezulu okushaya kwenhliziyo, afanele izinhlelo zokusebenza ezidinga ukuphuma kwamandla aphezulu. Ngakolunye uhlangothi, ama-fiber lasers, angakhiqiza ama-pulses ngamandla aphezulu ngokulungisa ubude bawo beza.

②Ubude be-Pulse (Ububanzi be-Pulse):
Ububanzi be-pulse bufushane, amandla aphezulu aphezulu ngesikhathi esinikeziwe, okuvumela amandla aphezulu okushaya kwenhliziyo. Ububanzi be-Pulse kuma-laser ashayayo ngokuvamile buyalungiseka phakathi kwama-nanoseconds nama-picoseconds, ngama-pulse amafushane asetshenziswa kakhulu ezinhlelweni ezisebenza ngokunemba okuphezulu ngenxa yamandla awo aphezulu.

③Amandla e-Laser kanye Nempumelelo Yokuguqula Amandla:
Ukusebenza kahle kwe-laser kunquma ngokuqondile ukuphuma kwamandla. Amanye amasistimu e-laser angathuthukisa ukusebenza kahle kokuguqulwa ngokuthuthukisa idizayini ye-gain medium noma i-laser cavity, ngaleyo ndlela andise amandla okushaya kwenhliziyo.

④I-Laser Amplifier:
Ezinhlelweni eziningi ze-laser ezinamandla amakhulu, ama-amplifiers asetshenziswa ukukhulisa amandla aphumayo. Ngokukhulisa izigaba eziningi, amandla okushaya kwenhliziyo angakhuliswa kakhulu.

⑤I-Laser Drive Yamanje:
Idrayivu yamanje ye-laser diode noma isistimu ye-laser iyisici esibalulekile esithonya amandla ayo okukhipha kanye namandla okushaya kwenhliziyo. Ngokulungisa yamanje, isimo sokuthakazelisa se-laser singashintshwa, ngaleyo ndlela sibe nomthelela ophumayo wamandla okushaya kwenhliziyo.

3. Izicelo Laser Pulse Energy

Ubukhulu be-laser pulse energy bunquma ukufaneleka kwayo emikhakheni ehlukene. Ezinye izinhlelo zokusebenza ezijwayelekile zifaka:

①Ukucubungula Okubalulekile:
Ku-laser welding, ukusika, kanye nokuqoshwa, amandla e-pulse angalawulwa ngokunembile ukuze kuzuzwe ukucubungula okusebenzayo nokunemba okuphezulu. Amandla e-higher pulse afanele ukucubungula izinto zensimbi, kuyilapho ama-pulse ane-low-energy asetshenziselwa ukwelapha okuphezulu.

②Izicelo Zokwelashwa:
Ama-laser ama-pulsed asetshenziswa kakhulu emkhakheni wezokwelapha, ikakhulukazi ukuhlinzwa kwe-laser, ukwelapha isikhumba, nokwelashwa kwamehlo. Isibonelo, ama-laser ashaywayo anamandla aphakeme angagxilisa amandla e-laser obude obuthile ezindaweni ezincane ukuze akhiphe izicubu ezigulayo noma ekwelapheni izimo zamehlo.

③I-LiDAR Nokuzwela Kukude:
Ubuchwepheshe be-LiDAR buncike kuma-laser wamandla we-pulse ephezulu ukuze uthole ukulinganisa okunembile nokucabanga. Ekuqaphelweni kwemvelo, ukushayela okuzenzakalelayo, kanye nokubhekwa kwe-drone, usayizi wamandla we-pulse uthinta ngokuqondile ibanga lokuthola nokuxazulula uhlelo lwe-LiDAR.

④Ucwaningo Lwesayensi:
Ama-laser ane-pulsed nawo adlala indima ebalulekile ekuhlolweni kwe-physics, chemistry, kanye ne-biology. Ngokulawula ngokunembile amandla okushaya kwenhliziyo, ososayensi bangakwazi ukwenza i-spectroscopy eyenziwe nge-laser enembayo, ukusheshiswa kwezinhlayiyana, kanye nocwaningo lokupholisa nge-laser.

4. Izindlela Zokukhuphula Amandla Okugadla

Izindlela ezijwayelekile zokwandisa amandla we-laser pulse zihlanganisa:

①Zuza Ukuthuthukisa Okumaphakathi:
Ngokukhetha indlela yokuzuza efanele kanye nokwenza kahle ukwakheka kwe-laser cavity, amandla okukhipha i-laser angandiswa.

②I-Multi-Stage Laser Amplification:
Ama-amplifiers anezigaba eziningi angakhuphula kancane kancane amandla e-laser ukuze ahlangabezane nezidingo zezinhlelo zokusebenza ezahlukene.

③Ukwandisa Ububanzi Bedrayivu Yamanje noma I-Pulse:
Ukulungisa idrayivu ye-laser yamanje noma ububanzi be-pulse kungaholela emandleni amakhulu e-pulse.

④I-Pulse Compression Technology:
Ngokusebenzisa amasu okucindezela i-pulse, ubude be-pulse bungafinyezwa, kwandise amandla alo aphezulu futhi kukhishwe amandla engeziwe ngesikhathi esifushane.

5. Isiphetho

I-Laser pulse energy iyipharamitha eyinhloko enomthelela ngokuqondile ekusebenzeni nasekusetshenzisweni kwama-lasers emikhakheni ehlukahlukene. Ngokuthuthuka okuqhubekayo kubuchwepheshe be-laser, ama-laser ama-pulsed azosetshenziswa kabanzi ezimbonini eziningi. Kusukela ekwenzeni imishini enembile kuye kwezinzwa kude kanye nokwelashwa kwezokwelapha, ukuphuma kwamandla aphezulu kwama-laser ashaywayo kuvula amathuba amasha. Ukuqonda imiqondo eyisisekelo yamandla okushaya kwenhliziyo kanye nezici zawo ezinomthelela kungasiza ukwenza izinqumo zesayensi ezengeziwe lapho uklama futhi usebenzisa amasistimu e-laser.
