Simba reLaser rePulse

Simba rekurova kwemoyo relaser rinoreva simba rinotumirwa nekurova kwemoyo kwelaser pachikamu chenguva. Kazhinji, malaser anogona kuburitsa mafungu anoenderera mberi (CW) kana mafungu anorova, uye ekupedzisira anonyanya kukosha mumabasa akawanda akadai sekugadzirisa zvinhu, kuona kure, michina yekurapa, uye kutsvagisa kwesainzi. Kunzwisisa hunhu hwesimba rekurova kwemoyo relaser kwakakosha pakuvandudza mashandiro aro uye kuvandudza kushanda zvakanaka kwekushandisa.

1. Tsanangudzo uye Kuyera kwePulse Energy

Simba reLaser pulse isimba rinoburitswa neLaser pulse yega yega, rinowanzo kuyerwa mujoules (J). Kusiyana nemawave anoramba achienderera mberi (CW), mawave anoramba achitenderera anoburitsa simba munguva pfupi, uye hukuru hwesimba hunowanzoenderana nenguva yekurova kwemoyo (pulse width) uye simba repamusoro.

Simba repulse rinogona kuverengwa uchishandisa fomura inotevera: E = Ppeak × τ. Apo E iri simba rekurova kwemoyo (joules), Ppeak ndiyo simba guru rekurova kwemoyo (watts), uye τ ndiyo nguva yekurova kwemoyo (masekondi). Izvi zvinoreva kuti simba rekurova kwemoyo rine chekuita zvakananga nesimba guru uye upamhi hwekurova kwemoyo.

2. Zvinhu Zvinokanganisa Simba rePulse

Zvinhu zvakawanda zvinopesvedzera simba rekurova kwemoyo re laser, zvinosanganisira:

①Dhizaini yeLaser uye Rudzi:
Mhando dzakasiyana dzema laser dzinokanganisa saizi yesimba re pulse. Semuenzaniso, ma laser e solid-state anowanzo kupa simba re pulse rakawanda, rakakodzera mashandisirwo anoda simba guru rekuburitsa. Ma laser e fiber, kune rumwe rutivi, anogona kugadzira ma pulse ane simba guru nekugadzirisa wavelength yawo.

②Nguva yePulse (Upamhi hwePulse):
Kana upamhi hwepulse hupfupi, simba repeak rinokwira munguva yakatarwa, izvo zvinoita kuti simba repulse riwedzere. Upamhi hwepulse muma pulsed lasers hunowanzo gadziriswa pakati pe nanoseconds nema picoseconds, uye ma short pulses anoshandiswa zvakanyanya mumabasa akanyatsojeka nekuda kwesimba rawo repeak.

③Kushanda Kwesimba reLaser uye Kuchinja Simba:
Kushanda zvakanaka kwelaser kunosarudza zvakananga simba rinobuda. Mamwe masisitimu elaser anogona kuwedzera kushanda zvakanaka kwekushandura nekuvandudza dhizaini ye gain medium kana laser cavity, nokudaro achiwedzera simba rekurova kwemoyo.

④MaAmplifaya eLaser:
Mumasystem mazhinji elaser ane simba guru, ma amplifiers anoshandiswa kuwedzera simba rinobuda. Kuburikidza nekuwedzera simba rema "multi-stage", simba re "pulse" rinogona kuwedzerwa zvakanyanya.

⑤Laser Drive Yazvino:
Kufamba kwemagetsi kwe laser diode kana laser system chinhu chakakosha chinokanganisa simba rayo rekubuda uye simba rekurova kwemoyo. Nekugadzirisa simba remagetsi, mamiriro ekupisa kwe laser anogona kuchinjwa, nokudaro zvichikanganisa kubuda kwesimba rekurova kwemoyo.

3. Mashandisirwo eLaser Pulse Energy

Saizi yesimba re laser pulse ndiyo inosarudza kukodzera kwaro munzvimbo dzakasiyana. Mamwe mashandisirwo akajairika anosanganisira:

①Kugadziriswa Kwezvinhu:
Mukubatanidza, kucheka, uye kuveza ne laser, simba rekurova kwemoyo rinogona kudzorwa nemazvo kuti riwane kugadziriswa kwakanaka uye kwakanyatsojeka. Simba rekurova kwemoyo rakawanda rakakodzera kugadzirisa zvinhu zvesimbi, nepo kurova kwemoyo kusina simba rakawanda kuchishandiswa pakugadzirisa pamusoro payo.

②Maitiro Ekurapa:
MaLaser ane pulsed anoshandiswa zvakanyanya mukurapa, kunyanya pakuvhiyiwa nelaser, kurapwa kweganda, uye kurapwa kwemaziso. Semuenzaniso, maLaser ane pulsed ane simba rakawanda anogona kutarisisa simba relaser rema wavelengths akasiyana munzvimbo diki kuti abvise matishu ane chirwere kana kurapa matambudziko emaziso.

③LiDAR uye Kunzwa Kure:
Tekinoroji yeLiDAR inoshandisa malaser ane simba rekurova zvakanyanya kuti ikwanise kusiyanisa zvinhu nemafirimu nemazvo. Mukutarisa nharaunda, kutyaira wega, uye kutarisa madrone, saizi yesimba rekurova kwemoyo inokanganisa zvakananga daro rekuona uye kugadziriswa kweLiDAR system.

④Tsvagiridzo yeSainzi:
Malaser anoputika anoitawo basa rakakosha mukuyedza mufizikisi, kemesitiri, uye biology. Nekudzora simba rekurova kwemoyo nemazvo, masayendisiti anogona kuita ongororo yekuona mafambiro emhepo nemazvo, kukurumidza kwezvikamu, uye tsvakiridzo yekutonhodza kwemhepo nelaser.

4. Nzira dzekuwedzera simba rekufema

Nzira dzakajairika dzekuwedzera simba rekurova kwemoyo ne laser dzinosanganisira:

①Wana Kugadzirisa Pakati Nepakati:
Nekusarudza nzira yakakodzera yekuwana chiedza uye kugadzirisa dhizaini yelaser cavity, simba rekubuda kwelaser rinogona kuwedzerwa.

②Kuwedzera kweLaser mumatanho akawanda:
Maamplifier ane zvikamu zvakawanda anogona kuwedzera simba rekurova kwemoyo welaser zvishoma nezvishoma kuti asvike pazvinodiwa zvemashandisirwo akasiyana.

③Kuwedzera Kufara Kwemuchina Wekutyaira kana Kufara Kwekumhanya:
Kugadzirisa simba remagetsi relaser kana upamhi hwepulse kunogona kukonzera simba guru repulse.

④Tekinoroji yeKudzvanya Pulse:
Uchishandisa nzira dzekumanikidza pulse, nguva yekurova kwemoyo inogona kupfupikiswa, zvichiwedzera simba rayo guru uye zvichiburitsa simba rakawanda munguva pfupi.

5. Mhedziso

Simba reLaser pulse ndiro chinhu chakakosha chinokanganisa zvakananga mashandiro uye mashandisirwo emaLaser muminda yakasiyana-siyana. Nekufambira mberi kuri kuitwa muhunyanzvi hweLaser, maLaser ane pulse achava nemashandisirwo akawanda mumaindasitiri akawanda. Kubva pakugadzira nemazvo kusvika pakuona kure uye kurapwa, simba rakawanda rinobuda mumaLaser ane pulse rinovhura mikana mitsva. Kunzwisisa pfungwa huru dzesimba repulse uye zvinhu zvinoripesvedzera kunogona kubatsira kuita sarudzo dzesainzi pakugadzira nekushandisa masisitimu eLaser.
