Pulse simba re lasers

Simba remhepo revaderera rinoreva simba rinoendeswa ne laser pulse pachikamu chenguva. Kazhinji, lasers inogona kusimudzira mafungu anoenderera mberi (cw) kana anodzvanya mafungu, aine ekupedzisira anonyanya kukosha mune akawanda ekunyora, kure kunzwa, nhumbi dzekurapa, uye yekutsvaga kwesainzi. Kunzwisisa hunhu hwe laser pulse simba rakakosha rekugadzirisa maitiro ayo uye nekuvandudza kushanda kwekushandisa.

1. Tsanangudzo uye kuyerwa kwesimba remhepo

Laser pulse simba isimba rinoburitswa neega ega laser pulse, kazhinji kuyerwa mu joules (j). Kusiyana nemawaziri kuenderera mberi

Pulse simba rinogona kuverengerwa uchishandisa iyo inotevera formula: e = ppeak ×. Iko e is a pulse simba (joules), ppeak is the preak simba re pulse (watts), uye τ is the pulse nguva (masekondi). Izvi zvinoreva kuti simba rinoenderana zvakananga kune ese maviri epamusoro simba uye pulse upamhi.

2. Zvinhu zvinokanganisa pulse simba

Zvinhu zvinoverengeka zvinopesvedzera simba rekupusha reLaser, kusanganisira:

①Laser dhizaini uye mhando:
Mhando dzakasiyana dze lasers dzinokanganisa saizi yemuvhare. Semuenzaniso, solid-state lasers kazhinji inopa yakakwira pulse simba, yakakodzera kuti application inoda kukwidziridzwa simba remagetsi. Fiber lasers, kune rumwe rutivi, inogona kuburitsa pulses ine simba rakakwirira nekugadzirisa yavo wavelength.

②Pulse Nguva (Pulse Upamhi):
Iyo ipfupi iyo pulse upfu hwakakura, yakakwira simba repamusoro munguva yakapihwa, inobvumidza yakakwira pulse simba. Pulsing Bild

③Laser Simba uye Simba Shanduko Inobudirira:
Iko kugona kweiyo laser zvakananga kunosarudza iyo simba rekubuda. Mamwe masisitimu emasikati anogona kusimudzira kushandurwa kwekushanduka nekugadzirisa dhizaini yeiyo kuwana yepakati svikiro kana laser cavity, nekudaro inowedzera pulse simba.

④Laser amplifiers:
Mune yakawanda yakakwirira-simba laser masisitimu, amplifiers anoshandiswa kuwedzera simba rekubuda. Kuburikidza neakawanda-nhanho kukwiridzwa, iyo pulse simba inogona kuve yakawandisa.

⑤Laser drive razvino:
Dhiraivha iripo yeiyo laser diode kana laser system yakakosha kukurudzira simba rayo rekubuditsa uye pulse simba. Nekugadzirisa iyo iripo, iyo laser's inonakidza mamiriro inogona kushandurwa, saka inokanganisa iyo pulse simba rekubuda.

3. Zvikumbiro zve laser pulse simba

Saizi yeiyo laser pulse simba inotarisisa kwayo kukodzera kweminda dzakasiyana. Zvimwe zvinowanzoitika zvinosanganisira:

①Kugadziriswa kwezvinhu:
MuLaser Werged Simba repamusoro rakakodzera simba rakakodzera kugadzirisa zvinhu zvesimbi, nepo yakaderera-simba pulses inoshandiswa kune yakanaka nzvimbo yekurapa.

②Zvekurapa Zvekushandisa:
Pakasangana Lasers anoshandiswa zvakanyanya mumunda wekurapa, kunyanya kune yekuvhiya kwe laser, kurapwa kweganda, uye kurapwa kweshithalem. Semuenzaniso, inodhonza lasers ine simba repamusoro inogona kutarisa laser simba renzvimbo dzakasarudzika kune nzvimbo diki kune nzvimbo diki dzekuisa chirwere chekurwara kana kurapa maziso.

③Lidar uye Remote Sensing:
Lidar tekinoroji inovandudza pane yakakwira pulse simba lasers yekunyatso ranging uye kufungidzira. Mukutyaira kwezvakatipoteredza, kutyaira kwekutyaira, uye kuongororwa kweDrone, iyo Simba rePulse Simba rinobata zvakananga nezvekuonekwa kwekutarisa uye kugadzirisa kweiyo lidar system.

④Tsvagurudzo yesainzi:
Pakasvetuka lasers zvakare vanoitawo basa rakakosha mukuedza mufizikiki, chemistry, uye biology. Nekunyatso kudzora pulse simba, masayendisiti anogona kuitisa yakanyanya-chaiyo laser-yakakwenenzverwa spectroscopy, chidimbu chekusimudzira, uye laser inotonhorera yekutsvaga.

4. Nzira dzekuwedzera pulse simba

Nzira dzakajairika dzekuwedzera laser pulse simba rinosanganisira:

①Wana svikiro optimization:
Nekusarudza kuwana kwakakodzera svikiro uye optimizing dhizaini yeiyo laser cavity, iyo simba rekubuda kweiyo laser inogona kuwedzerwa.

②Multi-Stage Laser Amplization:
Multi-Stage Amplifiers inogona zvishoma nezvishoma kuwedzera simba remagetsi reiyo laser kusangana nezvinodiwa zvekushandisa zvakasiyana.

③Kuwedzera kutyaira zvazvino kana pulse uply:
Kugadzirisa iyo LASER's drive razvino kana pulse upfu hwakakosha kunogona kuguma nekukura kwesimba.

④Pulse Commontiology:
Kushandisa pulse compression matekiniki, iyo nguva yekuputika inogona kupfupikiswa, ichiwedzera simba rayo repamusoro uye kusunungura simba rakawanda munguva pfupi.

5. Mhedziso

Laser pulse simba iri kiyi paramende iyo inokanganisa zvakananga kuita uye kushandiswa kwe lasers muminda dzakasiyana siyana. Nekufambira mberi kufambira mberi muLaser Technology, inodhonzwa lasers ichave nekunyorera maindasitiri mazhinji mumaindasitiri akawanda. Kubva panyaniso yemakwikwi ekurira kure nekurapa kwekurapa, iyo yakakwira simba rakabudiswa renzvimbo dzinodzora dzinovhura mikana mitsva. Kunzwisisa pfungwa dzakakosha dzePulse simba uye zvinhu zvayo zvinobatsira zvinogona kubatsira kuita sarudzo dzesainzi paunenge uchigadzira uye kushandisa laser masisitimu.
