I-Pulse Energy of Lasers

Amandla we-pulse we-laser abhekisela emandleni adluliselwa yi-laser pulse ngeyunithi yesikhathi ngasinye. Imvamisa, ama-lasers angakhipha amaza aqhubekayo (cw) noma amaza adonswayo, ngokubaluleka kokugcina kubaluleke kakhulu kwizicelo eziningi njengokucubungula izinto ezibonakalayo, ukuzwela okukude, imishini yezokwelapha kanye nocwaningo lwesayensi. Ukuqonda izici ze-Laser Pulse Energy kubalulekile ukwenza kahle ukusebenza kwayo nokwenza ngcono ukusebenza kahle kohlelo lokusebenza.

1. Ukuchazwa nokukalwa kwamandla we-pulse

I-Laser Pulse Energy ngamandla amandla akhishwe yi-Laser Pulse ngayinye, evame ukukalwa kuma-joules (j). Ngokungafani nama-lasers aqhubekayo aqhubekayo (CW) ama-lasers akhipha amandla ngesikhathi esifushane, futhi ubukhulu bamandla buhlobene ngokujwayelekile nobubanzi be-pulse (ububanzi be-pulse) kanye namandla aphezulu.

I-Pulse Energy ingabalwa kusetshenziswa ifomula elandelayo: e = Ppeak ×. Lapho u-Enerse Energy (Joules), i-Ppeak amandla aphezulu we-Pulse (Watts), futhi i-nder ubude be-pulse (amasekhondi). Lokhu kusho ukuthi amandla okushayela ahlobene ngokuqondile namandla amakhulu womabili kanye nobubanzi be-pulse.

2. Izici ezithinta amandla we-pulse

Kunezici eziningana zithonya amandla we-pulse we-laser, kufaka phakathi:

①I-Laser Design and Type:
Izinhlobo ezahlukahlukene zama-lasers zithinta usayizi wamandla we-pulse. Isibonelo, ama-lasers aqinile wombuso ngokuvamile anikela ngamandla we-pulse aphezulu, alungele izinhlelo zokusebenza ezidinga ukuphuma kwamandla aphezulu. Ngakolunye uhlangothi, ama-lasers, ngakolunye uhlangothi, angakhiqiza ama-pulses anamandla aphezulu ngokulungisa i-wavelength yawo.

②Isikhathi sokushayela (ububanzi be-pulse):
Okufushane ububanzi be-pulse, kuphakama amandla aphezulu ngesikhathi esinikeziwe, okuvumela amandla aphezulu we-pulse. Pulse widths in pulsed lasers are typically adjustable between nanoseconds and picoseconds, with short pulses being widely used in high-precision applications due to their high peak power.

③Amandla we-Laser nokusebenza kahle kwamandla:
Ukusebenza kahle kwe-laser kunquma ngqo ukukhishwa kwamandla. Ezinye izinhlelo ze-laser zingathuthukisa ukusebenza kahle kokuguqulwa ngokwenza kahle ukwakheka kwe-inzuzo ephakathi noma i-laser cavity, ngaleyo ndlela kukhuphuke amandla we-pulse.

④I-Laser Amplifiers:
Kuzinhlelo eziningi zamandla we-laser ephezulu, ama-amplifiers asetshenziselwa ukukhulisa amandla okuphuma. Ngokukhulisa ama-multi-stage amplifiefication, amandla we-pulse angakhuphuka kakhulu.

⑤I-Laser Drive yamanje:
I-drive yamanje ye-laser diode noma uhlelo lwe-laser yisici esibalulekile esithonya amandla alo okukhipha namandla. Ngokushintsha okwakha kwamanje, isimo sokuxoxa se-laser singashintshwa, ngaleyo ndlela sithinte umphumela wamandla we-pulse.

3. Izicelo ze-Laser Pulse Energy

Ubukhulu be-laser pulse energy inquma ukufaneleka kwayo izinkambu ezahlukahlukene. Ezinye izinhlelo ezijwayelekile zifaka:

①Ukucutshungulwa okubonakalayo:
E-laser welding, ukusika, nokuqopha, amandla okushayela ama-pulse angalawulwa ngokunembile ukuze afinyelele ukucubungula okusebenzayo nokunemba okunembayo. Amandla we-High Pulse Energy alungele ukucubungula izinto zensimbi, kanti ama-pulses aphansi asetshenziselwa ukwelashwa okuhle.

②Izicelo zezokwelapha:
Ama-lasers afakwe echibini asetshenziswa kabanzi emkhakheni wezokwelapha, ikakhulukazi ukuhlinzwa kwe-laser, ukwelashwa kwesikhumba, kanye nokwelashwa kwe-ophthalmic. Isibonelo, ama-laser asezingeni eliphakeme anamandla aphezulu angagxila kumandla we-laser ama-wavelength athile angena ezindaweni ezincane zokuhambisa izicubu zezicubu noma ekwelapheni.

③I-Lidar ne-Resukuve Sensing:
Ubuchwepheshe be-lidar buthembela kuma-pulse ama-enamandla ama-laserser ngokunemba okuqondile nokucabanga. Ngokuqapha imvelo, ukushayela okuzimele, kanye nokubhekwa kwe-drone, usayizi wamandla we-pulse uthinta ngqo ibanga lokutholwa kanye nokuxazululwa kohlelo lwe-lidar.

④Ucwaningo lweSayensi:
I-Pulsed Lasers nayo idlala indima ebalulekile ekuhlolweni kwe-physics, chemistry, kanye ne-biology. Ngokulawula ngokunembile amandla we-PULSE, ososayensi bangaphatha ngokunemba okuphezulu kwe-laser-anget spectroscopy, izinhlayiyana zokusheshisa, kanye nocwaningo lwe-laser ukupholisa.

4. Izindlela zokwandisa amandla okushaya ngamandla

Izindlela ezijwayelekile zokwandisa amandla we-laser pulse afaka:

①Thola ukusebenza okuphakathi:
Ngokukhetha inzuzo efanelekile ephakathi nendawo nokwenza kahle ukwakheka kwe-laser cavity, amandla okukhipha we-laser angandiswa.

②I-Multi-Stage Laser Amplification:
Ama-Amplifiers aneziteji eziningi angakhuphula kancane kancane amandla okushaya kwe-laser ukuze ahlangabezane nezidingo zezicelo ezahlukahlukene.

③Ukwanda kwe-drive yamanje noma ububanzi be-pulse:
Ukulungisa ukushayela kwe-laser's drive yamanje noma ububanzi be-pulse kungaholela emandleni amakhulu we-pulse.

④Ubuchwepheshe be-Pulse Compression:
Usebenzisa amasu wokugxuma kwe-Pulse Compression, ubude be-pulse bungafushaniswa, bandise amandla abo aphezulu futhi bakhiphe amandla amaningi ngesikhathi esifushane.

5. Isiphetho

I-Laser Pulse Energy iyipharamitha esemqoka ethonya ngqo ukusebenza nokusetshenziswa kwama-lasers emikhakheni ehlukahlukene. Ngentuthuko eqhubekayo kubuchwepheshe be-laser, ama-lasers afakwe e-pulsed azoba nezicelo ezibanzi ezimbonini eziningi. Ukusuka ekuqopheni kwemishini ukuzwela okukude kanye nokwelashwa kwezokwelapha, okukhishwa kwamandla okuphezulu kwama-lasers e-pulsed avula amathuba amasha. Ukuqonda imiqondo eyisisekelo yamandla we-pulse kanye nezinto zawo ezithonya kungasiza ukwenza izinqumo eziningi zesayensi lapho ziklama futhi zisebenzisa amasistimu we-laser.
