FAC Technology Bakeng sa Diode Laser

Karolo ea bohlokoa ka ho fetisisa ea optical ka har'a litsamaiso tsa ho bopa marako ho li-laser tsa diode tse matla ke Fast-Axis Collimation optic. Lilense li entsoe ka khalase ea boleng bo holimo 'me li na le bokaholimo ba acylindrical. Phallo ea tsona e phahameng ea linomoro e lumella hore phallo eohle ea diode e kopanngoe ka boleng bo ikhethang ba mabone. Phetiso e phahameng le litšobotsi tse ntle tsa collimation li netefatsa maemo a holimo ka ho fetesisa a ho bopa ka bokhabane bakeng salisebelisoa tsa laser tsa diode.

Fast Axis Collimators ke lilense tse kopaneng, tse phahameng tsa ts'ebetso ea aspheric cylindrical tse etselitsoeng ho etsa sebopeho sa mabala kapa lisebelisoa tsa laser diode collimation. Meralo ea aspheric cylindrical le li-apertures tse phahameng tsa lipalo li lumella ho kopana ho ts'oanang ha tlhahiso eohle ea laser diode ha ho ntse ho boloka boleng bo phahameng ba mabone.

Ho kopana ha laser diode 

Li-diode tsa laser hangata li na le litšobotsi tse hlahisoang tse fapaneng haholo le mefuta e meng ea laser. Ha e le hantle, li hlahisa lihlahisoa tse fapaneng haholo ho e-na le ho hlahisa sekontiri se kopantsoeng. Ho feta moo, karohano ena ke asymmetrical; karohano e kholoanyane haholo ka sefofane perpendicular ho mekhahlelo e sebetsang ka har'a diode chip, bapisoa le sefofane bapileng le dikarolo tsena. Sefofane se fapa-fapaneng haholo se bitsoa "mohaho o potlakileng", ha karolo e ka tlaase ea ho fapana e bitsoa "sebaka se fokolang".

Ho sebelisa laser diode ka katleho hoo e ka bang kamehla ho hloka ho kopana kapa ho hlophisoa bocha ha borokho bona bo fapaneng, ba asymmetric. 'Me, hangata sena se etsoa ho sebelisoa li-optics tse arohaneng bakeng sa lilepe tse potlakileng le tse liehang ka lebaka la thepa ea tsona e fapaneng. Ho phethahatsa sena ka ts'ebetso ho hloka ts'ebeliso ea li-optics tse nang le matla sebakeng se le seng feela (mohlala, lilense tsa cylindrical kapa acircular cylindrical).
