Kunzwisisa Duty Cycle muSemiconductor Lasers: Iyo Yakakura Zvinoreva Kuseri kweDiki Parameter.

Mune yemazuva ano optoelectronic tekinoroji, semiconductor lasers inomira pachena neyakaomesesa chimiro, kugona kwakanyanya, uye nekukurumidza kupindura. Ivo vanoita basa rakakosha muminda senge kutaurirana, hutano, kugadzirwa kwemaindasitiri, uye kunzwa / kutarisa. Nekudaro, kana tichikurukura nezvekuita kwema semiconductor lasers, imwe inoita seyakapusa asi yakakosha zvakanyanya parameter-yebasa kutenderera-inowanzo furatirwa. Ichi chinyorwa chinonyura mune iyo pfungwa, kuverenga, zvinorehwa, uye inoshanda kukosha kwebasa kutenderera mune semiconductor laser masisitimu.

1. Chii Chinonzi Duty Cycle?

Duty cycle ireshiyo isina dimensionless inoshandiswa kutsanangura chikamu chenguva iyo laser iri mu "pa" mamiriro mukati meimwe nguva yechiratidzo chekudzokorora. Inonyanya kuratidzwa sechikamu chezana. Iyo formula ndeye: Duty Cycle=(Pulse Width/Pulse Period)×100%. Semuyenzaniso, kana laser inoburitsa 1-microsecond pulse pagumi mamicroseconds ega ega, basa rekutenderera ndere: (1 μs/10 μs)×100%=10%.

2. Sei Duty Cycle Yakakosha?

Kunyangwe ingori reshiyo, kutenderera kwebasa kunobata zvakananga iyo laser's thermal management, hupenyu hurefu, simba rekubuda, uye yakazara system dhizaini. Ngatiburitse kukosha kwayo:

① Thermal Management uye Chishandiso Hupenyu hwese

Mukushanda kwepamusoro-frequency pulsed, kutenderera kwepasi kunoreva nguva refu "kubva" pakati pemapurusi, iyo inobatsira laser kutonhora pasi. Izvi zvinonyanya kubatsira mune yakakwirira-simba maapplication, uko kudzora kutenderera kwebasa kunogona kuderedza kushushikana kwekupisa uye kuwedzera hupenyu hwechishandiso.

② Simba rekubuda uye Optical Intensity Control

Basa repamusoro rinoita kuti pave neavhareji ye optical kubuda, nepo kutenderera kwepasi kunoderedza avhareji yesimba. Kugadzirisa kutenderera kwebasa kunobvumira kugadzirisa zvakanaka kwesimba rinobuda pasina kushandura peak drive ikozvino.

③ Kupindura kweSystem uye Signal Modulation

Mukukurukurirana kwemaziso uye LiDAR masisitimu, kutenderera kwebasa kunokanganisa zvakananga nguva yekupindura uye modulation zvirongwa. Semuyenzaniso, mune pulsed laser kubva, kuseta iyo chaiyo yebasa kutenderera inovandudza echo chiratidzo chekuonekwa, ichivandudza ese ari maviri kuyerwa kurongeka uye frequency.

3. Mienzaniso Yekushandisa YeDuty Cycle

① LiDAR (Laser Detection uye Rangi)

Mune 1535nm laser inotenderera modules, yakaderera-basa-kutenderera, yakakwirira-peak pulse configuration inowanzoshandiswa kuve nechokwadi chekuonekwa kwehurefu-refu uye kuchengetedzwa kweziso. Duty cycles dzinowanzodzorwa pakati pe0.1% ne1%, kuenzanisa yakakwirira yepamusoro peak nekuchengetedza, inotonhorera kushanda.

② Medical Lasers

Mukushandisa senge dermatological kurapwa kana kuvhiyiwa kwelaser, kutenderera kwemabasa kwakasiyana kunoguma nemhedzisiro yekupisa uye mhedzisiro yekurapa. Yepamusoro yebasa kutenderera inokonzeresa kudziyisa, nepo yakaderera basa kutenderera inotsigira instantaneous pulsed ablation.

③ Industrial Material Processing

Mune laser yekumaka uye welding, kutenderera kwebasa kunokanganisa kuti simba rinoiswa sei mumidziyo. Kugadzirisa kutenderera kwebasa kwakakosha pakudzora kudzika kwekunyora uye kupinza welding.

4. Nzira yeKusarudza Yakakodzera Duty Cycle?

Iyo yakakwana yebasa kutenderera inoenderana neiyo chaiyo application uye laser maitiro:

①Low Duty Cycle (<10%)

Yakanakira yakakwirira-peak, pfupi-pulse application senge kutara kana kunyatsomaka kumaka.

②Medium Duty Cycle (10%–50%)

Inokodzera yakakwirira-inodzokorora pulsed laser systems.

③High Duty Cycle (>50%)

Kusvika painoenderera mberi wave (CW) mashandiro, anoshandiswa mumashandisirwo senge optical kupomba uye kutaurirana.

Zvimwe zvinhu zvekufunga nezvazvo zvinosanganisira thermal dissipation kugona, mutyairi wedunhu kuita, uye laser's thermal kugadzikana.

5. Mhedziso

Kunyangwe idiki, iyo yebasa kutenderera chinhu kiyi dhizaini dhizaini mune semiconductor laser masisitimu. Izvo zvinokanganisa kwete kungobuda kwekuita asiwo kugadzikana kwenguva refu uye kuvimbika kwehurongwa. Mune ramangwana rekuvandudza laser uye mashandisiro, kunyatso kudzora uye kuchinjika kushandiswa kwebasa kutenderera kuchave kwakakosha mukusimudzira mashandiro ehurongwa nekugonesa hunyanzvi.

Kana uine mimwe mibvunzo nezve laser parameter dhizaini kana maapplication, inzwa wakasununguka kusvika kana kusiya mhinduro. Tauya kuzobatsira!
