Layisi ya UV ey’amakolero mu Frankfurt

Ebikwata ku kkampuni ya Frankfurt Laser (FLC)

Yatandikibwawo mu 1994, ng’ekitebe kyayo kisangibwa mu kibuga Frankfurt ekya Bugirimaani.

Tekinologiya omukulu: Essira lisse ku layisi za semiconductor (laser diodes), nga zirina obuwanvu bw’amayengo okuva ku 266nm okutuuka ku 16μm n’amaanyi okuva ku 5mW okutuuka ku 3000W28.

Ebikwata ku bikozesebwa:

Okuwa eby’okugonjoola ebizibu bya layisi ebikoleddwa ku mutindo gw’amagye, eby’omu bwengula, eby’obujjanjabi, eby’amakolero n’ebirala13.

Jaguza emyaka 30 mu 2024 era ogende mu maaso n’okutumbula obuyiiya bwa tekinologiya wa layisi1.

2. FLC UV Laser Ebintu Layini

(1) UV Laser Diode (Dayodi ya Layisi).

Ekyokulabirako eky’ekyokulabirako:

FWSL-375-150-TO18-MM: 375nm multimode UV laser diode, amaanyi agafuluma 150mW, asaanira eby'obujjanjabi, amakolero okuwonya, etc.1.

FVLD-375-70S: 375nm single-mode UV laser diode, 70mW output, okupima obulungi ennyo mu maaso, lithography, n’ebirala 46.

Obuwanvu bw’amayengo: 375nm–420nm (okumpi ne ultraviolet, NUV), ebintu ebimu bisobola okugaziwa okutuuka ku 266nm (deep ultraviolet, DUV) 68.

Ebitundu by’okusaba:

Obusawo: obujjanjabi bw’endwadde z’olususu, okuzaala n’okutta obuwuka (280–315nm MUV) 1.

Amakolero: Okuwonya UV (nga yinki, ebizigo), micromachining entuufu (nga okusala safiro) 17.

Okunoonyereza kwa ssaayansi: microscopy eya fluorescence, semikondokita lithography (<280nm FUV/VUV) 16.

(2) Layisi ya picosecond eya UV pulse ey’amaanyi amangi

Omuze: FPYL-Q-PS omusomo gwa 3.

Ebipimo:

Obuwanvu bw’amayengo: 266nm (1–8W), 355nm (1–50W).

Obugazi bwa pulse <10ps, frequency y’okuddiŋŋana 1MHz, amaanyi ag’oku ntikko 100W.

Okusaba:

Okulongoosa ebintu ebikalu (safiro, seramiki, OLED).

Amakolero ga semiconductor (okusala wafer, okusima micro)37.

3. Ebirungi ebikulu ebya UV laser

Okukola mu ngeri entuufu ennyo:

Layisi ya UV erina obuwanvu bw’amayengo obumpi (nga 355nm), esobola okutuuka ku kukola ku ddaala lya micron (minimum aperture 60μm), esaanira ebintu ebikalu n’ebimenyamenya nga safiro ne dayimanda7.

Zooni entono ekoseddwa ebbugumu, ekendeeza enjatika z’ebintu (bw’ogeraageranya ne layisi ya CO2)7.

Tekinologiya w’okulongoosa mu nnyonta:

Esaanira ebintu ebiwulikika ebbugumu (nga enzirukanya ezikyukakyuka, ebitundu ebiramu)37.

Okukozesebwa mu makolero:

Layisi ya FLC eya UV ewagira okupakinga okukoleddwa ku mutindo (TO, butterfly, fiber coupling), era ekwatagana n’embeera enzibu (nga ebbugumu eringi, okukankana)48.

4. Tekinologiya ayinza okukwatagana: EdgeLight nga egattibwa ne UV laser

Mu pulojekiti ya KonFutius (eyakulemberwa Fraunhofer IPT), layisi za UV zaakozesebwa okusala obulungi n’okuweta ebipande by’amataala ga Edgelight, okudda mu kifo ky’enkola z’okusiiga ez’ennono n’okutumbula obulungi13.

5. Okumaliriza

FLC's UV laser diodes ne picosecond UV laser zabikka dda ku nkola ezifaanagana ez'omulembe. Bw’oba ​​weetaaga parameters enzijuvu ku model entongole, kirungi okutuukirira ttiimu yaffe ey’abatunzi butereevu
