A fasahar zamani ta optoelectronic, na'urorin laser na semiconductor sun shahara da tsarinsu mai sauƙi, inganci mai yawa, da kuma saurin amsawa. Suna taka muhimmiyar rawa a fannoni kamar sadarwa, kiwon lafiya, sarrafa masana'antu, da kuma gano/ragewa. Duk da haka, idan ana maganar aikin na'urorin laser na semiconductor, sau da yawa ana yin watsi da wani siga mai sauƙi amma mai matuƙar muhimmanci - zagayowar aiki - wanda galibi ba a yin la'akari da shi. Wannan labarin ya zurfafa cikin ra'ayi, lissafi, abubuwan da suka shafi, da kuma mahimmancin zagayowar aiki a cikin tsarin na'urorin laser na semiconductor.
1. Menene Zagayen Aiki?
Zagayen aiki rabo ne mara girma wanda ake amfani da shi don bayyana rabon lokacin da laser yake cikin yanayin "kunna" a cikin lokaci ɗaya na siginar maimaituwa. Yawanci ana bayyana shi a matsayin kashi. Tsarin shine: Zagayen Aiki = (Faɗin Pulse)/Lokacin Bugawa) × 100%. Misali, idan na'urar laser ta fitar da bugun microsecond 1 a kowace microsecond 10, zagayowar aikin shine: (1 μs/10 μs) × 100%=10%.
2. Me Yasa Zagayen Aiki Yake Da Muhimmanci?
Duk da cewa rabo ne kawai, zagayen aiki yana shafar tsarin sarrafa zafi na laser, tsawon rai, ƙarfin fitarwa, da kuma tsarin gabaɗaya. Bari mu faɗi mahimmancinsa:
① Gudanar da Zafi da Rayuwar Na'ura
A cikin ayyukan bugun jini mai yawan mita, ƙaramin zagayen aiki yana nufin tsawon lokacin "kashewa" tsakanin bugun jini, wanda ke taimakawa laser ya huce. Wannan yana da amfani musamman a aikace-aikacen wutar lantarki mai ƙarfi, inda sarrafa zagayowar aiki zai iya rage damuwa ta zafi da tsawaita rayuwar na'urar.
② Ikon fitarwa da Ikon Tsananin gani
Zagayen aiki mafi girma yana haifar da matsakaicin fitarwa na gani, yayin da ƙaramin zagayen aiki yana rage matsakaicin ƙarfin aiki. Daidaita zagayowar aiki yana ba da damar daidaita kuzarin fitarwa ba tare da canza wutar lantarki mai ƙarfi ba.
③ Amsar Tsarin da Daidaita Sigina
A cikin sadarwa ta gani da tsarin LiDAR, zagayowar aiki kai tsaye yana tasiri ga lokacin amsawa da tsare-tsaren daidaitawa. Misali, a cikin kewayon laser mai bugun jini, saita zagayowar aiki mai kyau yana inganta gano siginar echo, yana haɓaka daidaiton ma'auni da mita.
3. Misalan Aikace-aikace na Zagayen Aiki
① LiDAR (Ganowa da Range na Laser)
A cikin na'urori masu auna laser na 1535nm, yawanci ana amfani da tsarin bugun jini mai ƙarancin aiki, mai tsayi don tabbatar da gano nesa mai nisa da amincin ido. Sau da yawa ana sarrafa zagayowar aiki tsakanin 0.1% da 1%, tare da daidaita ƙarfin kololuwar da aiki mai aminci da sanyi.
② Lasers na Likita
A aikace-aikace kamar maganin fata ko tiyatar laser, zagayowar aiki daban-daban yana haifar da tasirin zafi daban-daban da sakamako na warkewa. Tsarin aiki mai yawa yana haifar da dumama mai ɗorewa, yayin da tsarin aiki mai ƙarancin aiki yana tallafawa cirewar bugun zuciya nan take.
③ Masana'antu Kayan Aiki
A cikin alamar laser da walda, zagayowar aiki yana shafar yadda ake saka kuzari a cikin kayan aiki. Daidaita zagayowar aiki shine mabuɗin sarrafa zurfin sassaka da shigar walda.
4. Yadda Ake Zaɓar Tsarin Aiki Mai Kyau?
Mafi kyawun tsarin aiki ya dogara da takamaiman aikace-aikacen da halayen laser:
①Zagaye Mai Ƙarancin Aiki (<10%)
Ya dace da aikace-aikacen babban kololuwa, gajerun bugun jini kamar alamar jere ko daidaito.
②Matsakaicin Zagaye na Aiki (10%–50%)
Ya dace da tsarin laser mai yawan maimaitawa.
③Babban Zagaye Mai Aiki (>50%)
Ana kusantar da aikin ci gaba da amfani da raƙuman ruwa (CW), wanda ake amfani da shi a aikace-aikace kamar famfo na gani da sadarwa.
Sauran abubuwan da za a yi la'akari da su sun haɗa da ƙarfin watsawar zafi, aikin da'irar direba, da kuma daidaiton zafin laser.
5. Kammalawa
Ko da yake ƙarami ne, zagayowar aikin muhimmin ma'auni ne na ƙira a cikin tsarin laser na semiconductor. Ba wai kawai yana shafar fitowar aiki ba, har ma da kwanciyar hankali da amincin tsarin na dogon lokaci. A cikin haɓaka da amfani da laser a nan gaba, ingantaccen iko da sauƙin amfani da zagayowar aiki zai zama mahimmanci don haɓaka ingancin tsarin da kuma ba da damar ƙirƙira.
Idan kuna da ƙarin tambayoyi game da ƙirar sigogin laser ko aikace-aikace, jin daɗin tuntuɓar ko barin sharhi. Muna nan don taimakawa!
