Kwiinkalo ze-laser ukusuka, ukutyunjwa okujoliswe kuyo, kunye ne-LiDAR, i-Er: Izidluliseli ze-laser zeglasi ziye zasetyenziswa ngokubanzi i-laser ye-infrared solid-state lasers ngenxa yokhuseleko lwamehlo olugqwesileyo kunye noyilo oluhlangeneyo. Phakathi kweeparamitha zabo zokusebenza, amandla e-pulse adlala indima ebalulekileyo ekumiseleni ukukwazi ukubona, ukugubungela uluhlu, kunye nokuphendula kwenkqubo ngokubanzi. Eli nqaku linika uhlalutyo olunzulu lwe-pulse energy ye-Er:Izidluliseli zeglasi zeglasi.

1. Yintoni i-Pulse Energy?

Amandla e-Pulse abhekisa kumthamo wamandla akhutshwa yilaser kwi-pulse nganye, ngokuqhelekileyo elinganiselwa kwiimilijoules (mJ). Yimveliso yamandla aphezulu kunye nobude be-pulse: E = P_incopho×τ. Kuphi: E ngamandla e-pulse, P_incopho ngamandla aphezulu,τ bububanzi bokubetha kwentliziyo.

Kwi-Er eqhelekileyo: Iilaser zeglasi ezisebenza kwi-1535 nm-ubude bemaza kwiBand ye-1 ekhuselekileyo yamehlo-amandla aphezulu e-pulse anokufezekiswa ngelixa ugcina ukhuseleko, ubenza ukuba bafaneleke ngokukodwa kwizicelo eziphathekayo nangaphandle.

2. Pulse Energy Range of Er:Glass Lasers

Kuxhomekeka kuyilo, indlela yempompo, kunye nesicelo esicetywayo, i-Er yorhwebo: Izidluliseli ze-laser zeglasi zibonelela nge-pulse enye yamandla ukusuka kumashumi eemicrojoules (μJ) ukuya kumashumi amaninzi eemilijoules (mJ).

Ngokubanzi, i-Er:Izidluliseli ze-laser zeglasi ezisetyenziswa kwiimodyuli ezincinci ezisusela kuluhlu lwamandla e-pulse ye-0.1 ukuya kwi-1 mJ.

Amandla e-pulse ephezulu akhokelela ekusebenzeni ngcono, ngakumbi phantsi kweemeko ezinzima ezifana neempawu zokubuya ezibuthathaka okanye ukuphazamiseka kokusingqongileyo kuluhlu olude.

3. Izinto ezichaphazela amandla e-Pulse

①UkuSebenza koMthombo wempompo

Er:Iilaser zeglasi zikholisa ukumponthwa ngeelaser diode (LDs) okanye izibane. Ii-LDs zibonelela ngokusebenza okuphezulu kunye nokubumbana kodwa zifuna ulawulo oluchanekileyo lwe-thermal kunye nokuqhuba isekethe.

②I-Doping Concentration kunye nobude bentonga

Izixhobo zokusingathwa ezahlukeneyo ezifana ne-Er:YSGG okanye i-Er:Yb:Iglasi iyahluka kumanqanaba azo e-doping kunye nokuzuza ubude, okuchaphazela ngqo umthamo wokugcina amandla.

③I-Q-Switching Technology

I-Passive Q-switching (umzekelo, nge-Cr: YAG crystals) yenza lula ulwakhiwo kodwa inikezela ngokuchaneka okulinganiselweyo kokulawula. Ukutshintsha okusebenzayo kwe-Q (umzekelo, ngeeseli zePockels) kunika uzinzo oluphezulu kunye nolawulo lwamandla.

④Ulawulo lweThermal

Kumandla aphezulu e-pulse, ukutshatyalaliswa kobushushu obusebenzayo kwi-laser rod kunye nesakhiwo sesixhobo kubalulekile ukuqinisekisa ukuzinza kwemveliso kunye nokuphila ixesha elide.
