Basic parameters yeLaser system
Munzvimbo dzakawanda dzekushandisa dzakadai sekugadzirisa zvinhu, kuvhiyiwa kwelaser uye kuona kure, kunyangwe paine akawanda marudzi emalaser masisitimu, vanowanzo govana mamwe akajairwa musimboti paramita. Kumisikidza yakabatana parameter terminology system inogona kubatsira kudzivirira kuvhiringidzika mukutaura uye kugonesa vashandisi kusarudza nekugadzirisa laser masisitimu uye zvikamu zvakaringana, nekudaro kusangana nezvinodiwa zveakananga mamiriro.
Basic parameters
Wavelength (zvakajairwa zvikamu: nm kusvika μm)
Wavelength inoratidza huwandu hwemasaisai emwenje anoburitswa nelaser munzvimbo. Mamiriro akasiyana ekushandisa ane zvakasiyana zvinodiwa zvewavelengths: Mukugadzirisa zvinhu, mwero wekunyudzwa kwezvinhu zvemawavelengths chaiwo unosiyana, izvo zvinozokanganisa maitiro ekugadzirisa. Mumashandisirwo ekunzwa ari kure, pane misiyano mukutorwa uye kukanganiswa kwemasaisai akasiyana nemhepo. Mumashandisirwo ekurapa, kutorwa kwema lasers nevanhu vemavara akasiyana eganda zvakare kunosiyana zvichienderana newavelength. Nekuda kwenzvimbo diki yakatarisa, mapfupi-wavelength lasers uyeLaser optical zvishandisoIva nemukana mukugadzira zvidiki uye zvakaringana zvimiro, zvichigadzira kushoma kweparipheral kudziyisa. Nekudaro, zvichienzaniswa nemalaser ane marefu marefu, anowanzo kudhura uye anokonzeresa kukuvara.
2. Simba nesimba (Common units: W kana J)
Simba reLaser rinowanzoyerwa mumawatts (W) uye rinoshandiswa kuyera kubuda kwema lasers anoenderera kana avhareji simba remapulsed lasers. Kune pulsed lasers, simba rekupuruzira rimwe chete rakanangana neavhareji simba uye inversely yakaenzana nekudzokorora frequency, neyuniti iri joule (J). Iyo yakakwira simba kana simba, iyo yakakwira mutengo welaser kazhinji, iyo yakakura kudiwa kwekupisa kupisa kuri, uye kuoma kwekuchengetedza kunaka kwesimbi kunowedzerawo saizvozvo.
Pulse energy = avhareji simba rekudzokorora mwero Pulse simba = avhareji simba rekudzokorora mwero
3. Pulse duration (Common units :fs to ms)
Nguva ye laser pulse, inozivikanwawo se pulse width, inowanzotsanangurwa senguva yainotoralasersimba rekukwira kusvika pahafu yehupamhi hwayo (FWHM) (Mufananidzo 1). Iyo pulse wide yeultrafast lasers ipfupi zvakanyanya, kazhinji kubva picoseconds (10⁻¹² masekonzi) kusvika kumaattoseconds (10⁻¹⁸ masekonzi).
4. Kudzokorora mwero (Common units :Hz kusvika MHZ)
Chiyero chekudzokorora kweapulsed laser(kureva, iyo pulse repetition frequency) inotsanangura huwandu hwemapurusi anoburitswa pasekondi, ndiko kuti, kudzokororwa kweiyo timing pulse spacing (Mufananidzo 1). Sezvambotaurwa, chiyero chekudzokorora chinopesana nemhepo yemhepo uye zvakananga kuenzana neavhareji simba. Kunyangwe chiyero chekudzokorora chinowanzoenderana neiyo laser kuwana yepakati, muzviitiko zvakawanda, mwero wekudzokorora unogona kusiyana. Iyo yakakwira chiyero chekudzokorora, ipfupi iyo yekudziya yekuzorodza nguva yepasi peiyo laser optical element uye yekupedzisira yakatarisa nzvimbo, nekudaro zvichiita kuti zvinhu zvipise nekukurumidza.
5. Hurefu hwekubatana (Common units :mm kusvika cm)
Lasers ane kuwirirana, izvo zvinoreva kuti kune hukama hwakagadzikana pakati pezvikamu zvezvikamu zvemunda wemagetsi panguva dzakasiyana kana nzvimbo. Izvi zvinodaro nekuti ma lasers anogadzirwa nekusimudzirwa emission, iyo yakasiyana nemamwe akawanda marudzi emwenje masosi. Munguva yese yekuparadzira maitiro, kubatana zvishoma nezvishoma kunopera simba, uye kureba kwekubatana kwe laser kunotsanangura chinhambwe icho kubatana kwayo kwechinguva kunochengetedza humwe huwandu.
6. Polarization
Polarization inotsanangura kutungamira kwemagetsi emagetsi emagetsi emagetsi, ayo anogara ari perpendicular kune kutungamira kwekuparadzira. Kazhinji, ma lasers ane mutsara polarized, zvinoreva kuti iyo yakaburitswa yemagetsi munda inogara ichinongedza munzira imwechete. Non-polarized light rinogadzira minda yemagetsi inonongedza kwakasiyana siyana. Dhigirii repolarization rinowanzo kuratidzwa sereshiyo yesimba remaziso maviri orthogonal polarization states, se100:1 kana 500:1.
