Pred kratkim je raziskovalna skupina profesorja Qiu Min z univerze Westlake uspešno razvila novo vrsto homogenega silicijevega karbida (4H-SIC) Superlens, ki ponuja novo rešitev problema s toplotnim premikom pri laserski obdelavi z visoko močjo .
Povezani članek je bil objavljen v naprednih materialih pod naslovom "4H-SIC Metalens: blažilni učinek toplotnega premika pri laserskem obsevanju z visoko močjo" .
Compared with conventional commercial objective lenses, this superlens maintains diffraction-limited focusing performance while showing excellent thermal stability. It can maintain stable performance under long-term high-power laser irradiation and is almost unaffected by thermal absorption. This achievement is due to the excellent properties of 4H-SiC materials, including high optical transmittance and refractive index, Visoka toplotna prevodnost, visoka trdota in odpornost na praske, zaradi česar je idealen material za visokozmogljive optične naprave .
The new superlens makes full use of the high thermal conductivity and low loss characteristics of 4H-SiC, effectively suppresses the thermal drift effect, and thus gets rid of the dependence on complex cooling systems. This technological breakthrough not only provides key support for high-power laser systems, but also brings new possibilities to many fields such as precision instrument manufacturing, polar exploration, aerospace, ETC ., zlasti na območjih z izjemno visokimi zahtevami za natančnost obdelave in kakovost površine . 4 H-SIC Superlens bodo igrali pomembno vlogo in zagotovili učinkovitejše in kompaktne rešitve za laserske aplikacije z visoko močjo .
Earlier, Westlake University also announced another breakthrough in silicon carbide technology: Westlake Instruments, incubated by Westlake University, successfully developed a 12-inch silicon carbide substrate automated laser stripping technology to solve the problem of slicing ultra-large silicon carbide substrates. The laser forms hundreds of millions of extremely fine "Točke razstreljevanja" znotraj materiala za samodejno odstranjevanje sloja ingot s plastjo . hitrost rezine se v primerjavi s tradicionalnim rezanjem bistveno izboljša, izguba materiala pa se zmanjša za 50%.
Ta dva preboja kažeta, da je univerza Westlake v mednarodnem vodilnem položaju pri raziskovanju aplikacij in tehnologije ter razvoju materialov iz silicijevega karbida in zagotavljata ključno tehnično podporo za laserske sisteme z visoko močjo, natančno proizvodnjo, vesoljsko in novo energetsko industrijo .
