Mapepala osewerera otsekedwa, mphamvu yayikulu kwambiri osema

Mphamvu zambiri femtundolaserAli ndi mtengo wofunikira pakufufuza zasayansi komanso minda yofananira monga mibadwo ya Teraherz, a Centcond mbadwo wokondwerera ndi chisa cha pafupipafupi.Ma laseji otsekekaKutengera ndi malo osungirako zachikhalidwe

Mapepala owonda amagwiritsa ntchito njira yodutsa pampu yambiriKuwalaKuti pepalalo lisapezeke bwino ndi makulidwe a Microns 100 ya Mipoption Mipaume. Wopsinjika kwambiri kupeza ndi ukadaulo wophatikizika ndi matekinoloje amachepetsa kwambiri kukomoka kwa ma lens a mandala komanso osakwanitsa, ndipo amatha kukwaniritsa mphamvu zapamwamba za femturosecond zotulutsa.
Ufa oscillators wophatikizidwa ndi ukadaulo wotsekera ndi ma kerr lens ndiye njira yayikulu yopezera mafuta okwera kwambiri a laser mu dongosolo la femptosecond.

Kutengera mfundo ya Kerr Lens lotseka komanso kuwerengera kwa ABCD Matrix, kafukufuku wotsekerako wotsekedwa pang'ono, ndikutsimikizira kuti mawonekedwe a diaphragm omwe ali pa diaphragm okwanira 7% atatseka mode.

Pambuyo pake, motsogozedwa ndi mfundo yopanga, gulu lofufuzira linapangidwa ndi malo otsekedwa a kerr lens (mkuyu. 2 M'lifupi mwake chotulutsa ndi kusiyanasiyana kwa njira ya intrakovacity ndi mgwirizano wabwino ndi zotsatira za mawu.

CHITH. Chithunzi chaching'ono cha 2 chojambulira cha kuwonekera kwa kerr lens mode - Yag Wafer lar amagwiritsa ntchito poyesera

Pofuna kukonza mphamvu ya laser, gulu lofufuzira linakweza makonda okutira a galasi, ndikuwonetsa bwino kerr sing'anga makulidwe ndi kupezeka kwachiwiri. Pamene mphamvu yopopera idakhazikitsidwa mpaka 94 w, mphamvu yayikulu yotulutsa idachulukana mpaka 22.33 w, ndipo mulifupi wa 394 fs 394 μj.

Kuti muwonjezere mphamvu yotulutsa, gulu lofufuzira lidzawonjezera makonda ophatikizika a kalasi yolumikizidwa, ndikuyika wotsutsa pamalo otsekeka kuti muchepetse vuto la mpweya.
