Coherent combining technology ntawm ultrashort mem tes

Rau lub zog siab ultrashort pulse laser, nws muaj txiaj ntsig zoo rau kev tshawb fawb tshawb fawb, kev tsim khoom lag luam thiab biomedical teb.Cov txheej txheem ntawm coherent combining technology ntawm ultrashort mem tes yog qhia raws li daim duab 1.

                                                           Daim duab 1 Pluse ua ke/split txoj kev

Laser noob mem tes yuav muab faib ua ob peb lub mem tes, tom qab ntawd nws lub zog yuav raug nthuav tawm los ntawm AMP, tag nrho cov pulse pulse yuav muab tso rau hauv ib qho kom nce siab zog thiab lub zog.Txhawm rau kom tsis txhob muaj cov nyhuv nonlinear, CPA thev naus laus zis yuav raug siv los nthuav dav laser noob mem tes ua ntej rau lub zog amplification, tom qab ntawd kom compress pulse dav.Muaj peb txoj hauv kev kom ua tiav kev sib koom ua ke ntawm kev sib txuas ntawm ultrashort mem tes: spatial coherent combining, faib-memplification (DPA), thiab mem tes pawg.

Nyob rau hauv cov nqe lus ntawm spatial coherent combining (daim duab 1(a)), qhov yooj yim technic yog tib yam li nruam laser.Laser noob muab faib los ntawm splitter, txhua qhov sib cais ib qho yog amplified los ntawm theem modulator thiab lub zog amplifier thiab thaum kawg ua ke ua ib qho kev koom ua ke.

Txoj kev thib ob yog DPA (daim duab 1(b)) uas faib cov mem tes laser rau hauv txhua qhov laser sib cais uas sib cais thiab tsis cuam tshuam los ntawm ib leeg.Cov txheej txheem laser no yuav ua ke rau hauv laser pulse kom nce siab tshaj plaws ntawm cov zis mem tes.

Pulse stack (daim duab 1(c)) tuaj yeem ua ntau cov pulses pawg rau hauv ib lub mem tes uas tuaj yeem ua tiav los ntawm GTI thiab SND (stack-and-dump).

Nws yog yuav luag tib lub sij hawm uas coherent combining thev naus laus zis thiab lasers tau tsim, uas tau txais txiaj ntsig tseem ceeb ntawm 10.3kw ultra-ceev fiber ntau laser coherent combining thiab 100-channel loj arrays fiber ntau laser coherent combining, thiab paub nws tus nqi ntawm laser zaus conversion, laser radar thiab laser qhia hnub qub.Tsis tu ncua hloov tshiab thev naus laus zis ntawm lasers muab lub teeb ci tshiab rau kev sib koom ua ke, rov qab los, nce luminance ntawm lub teeb pom kev vam khom rau kev sib koom ua ke thev naus laus zis.
