Zviyero zvekutanga zve laser system

Zviyero zvepakutanga zvesisitimu yelaser

Munzvimbo dzakawanda dzekushandisa dzakadai sekugadzirisa zvinhu, kuvhiyiwa kwelaser uye kuona kure, kunyangwe paine mhando dzakawanda dzemasisitimu elaser, anowanzo fanana nemamwe ma core parameter akafanana. Kugadzira sisitimu yemashoko akabatana kunogona kubatsira kudzivirira kuvhiringidzika mukutaura uye kugonesa vashandisi kusarudza nekugadzirisa masisitimu elaser nezvikamu zvakanyatsonaka, nokudaro zvichizadzisa zvinodiwa nemamiriro ezvinhu chaiwo.

Zviyero zvepakutanga

Hurefu hwemafungu (mayuniti akajairika: nm kusvika μm)

Hurefu hwemafungu hunoratidza hunhu hwemafungu echiedza anoburitswa nelaser muchadenga. Mamiriro akasiyana ekushandiswa ane zvinodiwa zvakasiyana zvemafungu: Mukugadzirisa zvinhu, mwero wekunyudzwa kwezvinhu zvemafungu chaiwo unosiyana, izvo zvinokanganisa mhedzisiro yekugadzirisa. Mukushandiswa kwekuona kure, pane musiyano mukunyudzwa uye kupindira kwemafungu akasiyana nemhepo. Mukushandiswa kwekurapa, kunyudzwa kwemalaser nevanhu vane mavara akasiyana eganda kunosiyanawo zvichienderana nehurefu hwemafungu. Nekuda kwenzvimbo diki yakatarisana, malaser mapfupi uyezvishandiso zve laser opticalane mukana wekugadzira zvinhu zvidiki uye zvakanyatsonaka, zvichiita kuti pave nekupisa kushoma kwazvo. Zvisinei, kana tichienzanisa nemalaser ane marefu ewavelength, anowanzo kudhura uye anogona kukuvara zvakanyanya.

2. Simba nesimba (Zvikamu zvakajairika: W kana J)

Simba reLaser rinowanzo kuyerwa mu watts (W) uye rinoshandiswa kuyera kubuda kwema laser anoenderera mberi kana avhareji yesimba rema laser anotenderera. Kune ma laser anotenderera, simba re pulse imwe chete rinoenderana zvakananga nesimba repakati uye rinoenderana ne frequency yekudzokorora, neyuniti iri joule (J). Simba kana simba rakawanda, mutengo we laser unowanzo kwira, zvinodiwa zvekuparadza kupisa zvakanyanya, uye kuoma kwekuchengetedza kunaka kwemwenje kunowedzerawo zvinoenderana.

Simba rekufema = chiyero chepakati pesimba rekudzokorora Simba rekufema = chiyero chepakati pesimba rekudzokorora

3. Nguva yekurova kwemoyo (Zviyero zvakajairika :fs kusvika ms)

Nguva yekurova kwemoyo kwelaser, inozivikanwawo sehupamhi hwekurova kwemoyo, inowanzotsanangurwa senguva inotora kutilaserSimba rekukwira kusvika hafu yehuremu hwayo (FWHM) (Mufananidzo 1). Upamhi hwepulse yemalaser e-ultrafast hupfupi zvikuru, hunowanzo tangira pamapicoseconds (10⁻¹² seconds) kusvika kumaattoseconds (10⁻¹⁸ seconds).

4. Mwero wekudzokorora (Zvikamu zvakajairika :Hz kusvika kuMHZ)

Mwero wekudzokorora kwelaser inoputika(kureva, frequency yekudzokorora kwepulse) inotsanangura huwandu hwemapulse anoburitswa pasekondi, ndiko kuti, kudzokororwa kwenzvimbo yekurova kwemoyo (Mufananidzo 1). Sezvambotaurwa, chiyero chekudzokorora chinoenderana nesimba rekurova kwemoyo uye chakanangana nesimba repakati. Kunyangwe chiyero chekudzokorora chinowanzoenderana ne laser gain medium, muzviitiko zvakawanda, chiyero chekudzokorora chinogona kusiyana. Kana chiyero chekudzokorora chakakwira, nguva yekuzorora kwekupisa kwepamusoro pechinhu che laser optical uye nzvimbo yekupedzisira yakatarisana, zvichiita kuti zvinhu zvikwanise kupisa nekukurumidza.

5. Kureba kwekubatana (Zviyero zvakafanana :mm kusvika cm)

MaLaser ane kubatana, zvinoreva kuti pane hukama hwakasimba pakati pezvikamu zvesimba remagetsi panguva dzakasiyana kana nzvimbo. Izvi zvinodaro nekuti maLaser anogadzirwa nekubuda kwechiedza, izvo zvakasiyana nemamwe marudzi mazhinji echiedza. Munguva yese yekupararira, kubatana kunopera simba zvishoma nezvishoma, uye kureba kwekubatana kweLaser kunotsanangura daro iro kubatana kwayo kwenguva inochengetedza huremu hwakati.

6. Kupatsanurana

Polarization inotsanangura divi remagetsi emagetsi emafungu echiedza, iro rinogara rakatarisa divi rekupararira. Kazhinji, ma lasers anowanzo patsanurwa, zvichireva kuti magetsi anoburitswa anogara akananga divi rimwe chete. Chiedza chisina polarized chinogadzira magetsi anonongedza mativi akasiyana-siyana. Dhigirii repolarization rinowanzo ratidzwa sechiyero chesimba re optical remamiriro maviri e orthogonal polarization, akadai se100:1 kana 500:1.
