I-Pulse Energy ye-Er:IziThuthi zeLaser zeglasi

Kwimiba yokulinganisa i-laser, ukuchongwa kwethagethi, kunye ne-LiDAR, ii-Er:Glass laser transmitters ziye zasetyenziswa kakhulu zii-mid-infrared solid-state lasers ngenxa yokhuseleko lwazo olugqwesileyo lwamehlo kunye noyilo oluncinci. Phakathi kweeparamitha zazo zokusebenza, amandla e-pulse adlala indima ebalulekileyo ekumiseleni amandla okufumanisa, ukugubungela umgama, kunye nokuphendula kwenkqubo iyonke. Eli nqaku libonelela ngohlalutyo olunzulu lwamandla e-pulse ee-Er:Glass laser transmitters.

1. Yintoni Amandla ePulse?

Amandla e-pulse abhekisa kubungakanani bamandla akhutshwa yi-laser kwi-pulse nganye, edla ngokulinganiswa kwi-millijoules (mJ). Yimveliso yamandla aphezulu kunye nobude be-pulse: E = P_incopho×τApho: U-E ngamandla okubetha kwentliziyo, u-P_incopho ngamandla aphezulu,τ bububanzi be-pulse.

Kwi-Er:Iilaser zeglasi eziqhelekileyo ezisebenza kwi-1535 nm—ubude bexesha kwibhendi ekhuselekileyo emehlweni yeKlasi 1—amandla aphezulu okubetha kwentliziyo anokufezekiswa ngelixa kugcinwa ukhuseleko, nto leyo eyenza ukuba zifaneleke ngakumbi kwiindlela eziphathwayo nezangaphandle.

2. Pulse Energy Range of Er:Glass Lasers

Ngokuxhomekeke kuyilo, indlela yokumpompa, kunye nokusetyenziswa okucwangcisiweyo, ii-Er:Glass laser transmitters zorhwebo zibonelela ngamandla e-single-pulse ukusuka kwi-10 yee-microjoules (μJ) ukuya kumashumi aliqela ee-millijoules (mJ).

Ngokubanzi, ii-Er:Glass laser transmitters ezisetyenziswa kwiimodyuli ezincinci zinoluhlu lwamandla e-pulse oluyi-0.1 ukuya kwi-1 mJ. Kwizinto ezijolise kuzo ezikude, kufuneka i-5 ukuya kwi-20 mJ, ngelixa iinkqubo zomkhosi okanye zemizi-mveliso zinokudlula i-30 mJ, zihlala zisebenzisa izakhiwo zokukhulisa iintambo ezimbini okanye ezinezigaba ezininzi ukuze kufezekiswe imveliso ephezulu.

Amandla aphezulu e-pulse adla ngokukhokelela ekusebenzeni ngcono kokubhaqwa, ingakumbi phantsi kweemeko ezinzima ezifana nemiqondiso yokubuya ebuthathaka okanye ukuphazamiseka kwendalo kwiindawo ezinde.

3. Izinto Ezichaphazela Amandla Okubetha Kwentliziyo

①Ukusebenza koMthombo weMpompo

I-Er: Iilaser zeglasi zihlala ziqhutywa zii-laser diodes (ii-LD) okanye ii-flashlight. Ii-LD zibonelela ngokusebenza kakuhle nangokucothayo kodwa zifuna ulawulo oluchanekileyo lwesekethe yobushushu kunye neyokuqhuba.

②Uxinzelelo lweDoping kunye nobude beNtonga

Izixhobo ezahlukeneyo zokusingatha ezifana ne-Er:YSGG okanye i-Er:Yb:Glass ziyahluka kumanqanaba azo okusebenzisa i-doping kunye nobude bokufumana amandla, nto leyo echaphazela ngokuthe ngqo amandla okugcina amandla.

③Itekhnoloji yokutshintsha i-Q

Ukutshintsha kwe-Q okungasebenziyo (umz., ngeekristale ze-Cr:YAG) kwenza kube lula ulwakhiwo kodwa kunika ulawulo oluchanekileyo. Ukutshintsha kwe-Q okusebenzayo (umz., ngeeseli zePockels) kunika uzinzo oluphezulu kunye nolawulo lwamandla.

④Ulawulo lobushushu

Xa amandla e-pulse ephezulu enyuka, ukuchithwa kobushushu okusebenzayo kwi-laser rod kunye nesakhiwo sesixhobo kubalulekile ukuqinisekisa uzinzo lwemveliso kunye nobude bexesha.

4. Ukuthelekisa Amandla ePulse kunye neMibono yeSicelo

Ukukhetha i-Er:Glass laser transmitter efanelekileyo kuxhomekeke kakhulu kwisicelo esicetywayo. Apha ngezantsi kukho iimeko eziqhelekileyo zokusetyenziswa kunye neengcebiso zamandla okubetha kwentliziyo ezifanelekileyo:
