Zviyero zvakakosha zvekutarisa mashandiro ehurongwa hwe laser

1. Hurefu hwemafungu (yuniti: nm kusvika μm)

Iyowavelength yelaserinomiririra kureba kwemafungu emagetsi anotakurwa nelaser. Zvichienzaniswa nedzimwe mhando dzechiedza, chinhu chakakosha chelaserndeyekuti ine magirazi maviri chete, zvinoreva kuti urefu hwemafungu ayo hwakachena uye ine mafrequency akatsanangurwa zvakanaka kamwe chete.

Musiyano uripo pakati pema wavelength akasiyana e laser:

Kureba kwemwaranzi mutsvuku kunowanzova pakati pe630nm-680nm, uye chiedza chinoburitswa chitsvuku, uye ndiyowo mwaranzi inonyanya kushandiswa (inonyanya kushandiswa mumunda wechiedza chekudyisa chekurapa, nezvimwewo);

Hurefu hwemafungu egirini laser hunowanzoita 532nm, (hunonyanya kushandiswa mumunda wekushandisa laser, nezvimwewo);

Kureba kwebvudzi rebhuruu relaser kunowanzova pakati pe400nm-500nm (kunonyanya kushandiswa pakuvhiya nelaser);

Laser yeUv iri pakati pe350nm-400nm (inonyanya kushandiswa mukurapa kwezvipenyu);

Laser yeinfrared ndiyo inonyanya kukosha, zvichienderana nehuwandu hwewavelength uye nzvimbo yekushandisa, urefu hwewavelength yelaser yeinfrared hunowanzo kuwanikwa pakati pe700nm-1mm. Bhandi reinfrared rinogona kukamurwa kuita zvikamu zvitatu: near infrared (NIR), middle infrared (MIR) uye far infrared (FIR). Urefu hwewavelength yeinfrared hunosvika 750nm-1400nm, iyo inoshandiswa zvakanyanya mukukurukurirana kwefiber, biomedical imaging uye infrared night vision michina.

2. Simba nesimba (chikamu: W kana J)

Simba reLaserinoshandiswa kutsanangura simba remagetsi rinobuda kubva ku-continuous wave (CW) laser kana kuti simba remagetsi rinobuda kubva ku-pulsed laser. Pamusoro pezvo, ma-pulsed laser anoratidzwa nekuti simba remagetsi rawo rinoenderana nesimba remagetsi uye rinoenderana ne-repeat rate ye-pulse, uye ma-laser ane simba rakawanda anowanzo buritsa kupisa kwakawanda.

Mazhinji emarasha elaser ane chimiro cheGaussian beam profile, saka kupenya nekuyerera kwechiedza zviri pamusoro pe optical axis yelaser uye zvinodzikira sezvo kutsauka kubva ku optical axis kuchiwedzera. Mamwe marasha ane ma flat-top beam profiles ayo, kusiyana neGaussian beams, ane chimiro che irradiance chinogara chiripo pakati pechikamu che laser beam uye kudzikira kwesimba nekukurumidza. Nokudaro, ma flat-top laser haana peak irradiance. Simba repamusoro reGaussian beam rinopetwa kaviri kupfuura flat-top beam rine avhareji yakafanana yesimba.

3. Nguva yekurova kwemoyo (chikamu: fs kusvika ms)

Nguva yekurova kwemoyo kwelaser (kureva upamhi hwekurova kwemoyo) inguva inotora kuti laser isvike hafu yesimba guru remaoptical (FWHM).

 

4. Kudzokorora kwehuwandu (chikamu: Hz kusvika MHz)

Mwero wekudzokorora kwelaser inoputika(kureva kuti chiyero chekudzokorora kwekurova kwemoyo) chinotsanangura huwandu hwemapulse anoburitswa pasekondi, ndiko kuti, kudzokororwa kwenzvimbo yekurova kwemoyo panguva. Chiyero chekudzokorora chinoenderana nesimba rekurova kwemoyo uye chinoenderana nesimba repakati. Kunyangwe chiyero chekudzokorora chinowanzoenderana nepakati pe laser gain, muzviitiko zvakawanda, chiyero chekudzokorora chinogona kuchinjwa. Chiyero chepamusoro chekudzokorora chinoita kuti nguva yekuzorora kwekupisa ive pfupi pamusoro uye kutarisisa kwekupedzisira kwechinhu che laser optical, izvo zvinotungamira mukudziya kukuru kwezvinhu.

5. Kusiyana (chinowanzoitwa: mrad)

Kunyangwe matanda elaser achiwanzoonekwa seanoungana, anogara aine musiyano wakati, izvo zvinotsanangura kuti danda rinopatsanuka sei pamusoro pechinhambwe chinowedzera kubva muchiuno chedanda relaser nekuda kwekupararira. Mukushandiswa kune madaro marefu ekushanda, akadai se liDAR systems, uko zvinhu zvingave zviri mazana emamita kure nehurongwa hwelaser, musiyano unova dambudziko rakakosha zvikuru.

6. Saizi yenzvimbo (yuniti: μm)

Saizi yedanda relaser rakananga rinotsanangura dhayamita yedanda panzvimbo yefocus yelens system. Muzvishandiso zvakawanda, zvakaita sekugadzirisa zvinhu uye kuvhiyiwa kwechiremba, chinangwa ndechekuderedza saizi yedanda. Izvi zvinowedzera simba uye zvinobvumira kugadzirwa kwezvinhu zvakanyatsonaka. Magirazi eAspherical anowanzo shandiswa panzvimbo pemagirazi echinyakare edenderedzwa kuderedza kushanduka kwedenderedzwa uye kugadzira saizi diki yedenderedzwa.

7. Kureba kwekushanda (yuniti: μm kusvika m)

Daro rekushanda kwesystem yelaser rinowanzotsanangurwa sedaro repanyama kubva pachinhu chekupedzisira che optical (kazhinji lenzi inotarisa) kuenda kuchinhu kana pamusoro pacho iyo laser inotarisa. Mamwe mashandisirwo, akadai sema laser ekurapa, anowanzo tsvaga kuderedza dariro rekushanda, nepo mamwe, akadai sekuona kure, anowanzo tarisa kuwedzera daro rawo rekushanda.
