Nezve MOPA

MOPA (Master Oscillator Power Amplifier) ​​inyanzvi yekugadzira laser inowedzera kushanda kwemagetsi nekuparadzanisa sosi yembeu (master oscillator) kubva padanho rekuwedzera simba. Pfungwa huru inosanganisira kugadzira chiratidzo chembeu chemhando yepamusoro nemaster oscillator (MO), iyo inozowedzerwa simba nepower amplifier (PA), pakupedzisira ichipa ma pulses elaser ane simba guru, emhando yepamusoro, uye emhando yepamusoro. Iyi hunyanzvi inoshandiswa zvakanyanya mukugadzira maindasitiri, kutsvagisa kwesainzi, uye kushandiswa kwekurapa.

1.Mabhenefiti Akakosha eMOPA Amplification

①Maparamita Anochinjika uye Anodzoreka:

- Hupamhi hwePulse Hunogona Kugadziriswa Hwakazvimirira:

Upamhi hwekurova kwemoyo kwembeu hunogona kugadziriswa pasina kuenderana nedanho reamplifier, rinowanzo bva pa1 ns kusvika 200 ns.

- Chiyero Chekudzokorora Chinogona Kugadziriswa:

Inotsigira huwandu hwakasiyana hwema "pulse repetition rates", kubva pa "single-shot" kusvika pa "MHz-level high-frequency pulses", kuti isangane nezvinodiwa zvakasiyana-siyana zvekugadzirisa (semuenzaniso, "high-speed marking" uye "deep engraving").

②Hunhu Hwakakwirira hweBeam:
Hunhu hwembeu husina ruzha rwakanyanya hunochengetwa mushure mekuwedzerwa simba, zvichipa mhando yemwaranzi inogumira kupararira (M² < 1.3), yakakodzera kushandiswa nemazvo.

③Simba reKurova Kwakanyanya uye Kugadzikana:
Nekuwedzera simba remagetsi muzvikamu zvakawanda, simba remagetsi rimwe chete rinogona kusvika padanho remamiriyoni nekuchinja-chinja kwesimba kushoma (<1%), izvo zvakanaka kwazvo kumashandisirwo emaindasitiri akanyatsogadzirwa.

④Kugona Kugadzira Cold:
Nekureba kwemoyo kupfupi (semuenzaniso, mu nanosecond range), mhedzisiro yekupisa pazvinhu inogona kuderedzwa, zvichiita kuti zvinhu zvinoputsika-putsika zvive nyore kugadzira.

2. Master Oscillator (MO):

MO inogadzira mbeu dzine simba shoma asi dzakanyatsodzorwa. Nzvimbo yembeu inowanzova semiconductor laser (LD) kana fiber laser, inogadzira pulses kuburikidza nekushandura zvakananga kana kwekunze.

3.Chikungurutsiri cheSimba (PA):

PA inoshandisa maamplifiers efiber (akadai seytterbium-doped fiber, YDF) kuti iwedzere kuyerera kwembeu muzvikamu zvakasiyana-siyana, zvichiwedzera simba repulse zvakanyanya uye simba repakati. Dhizaini yeamplifier inofanira kudzivirira mhedzisiro isiri yemutsara yakaita seyakakurudzira Brillouin scattering (SBS) uye yakakurudzira Raman scattering (SRS), uku ichichengetedza mhando yepamusoro yemwaranzi.
