Kodi laser ya CW DPSS ndi chiyani? Tanthauzo Kusanthula

Mafunde Osalekeza (CW):Izi zikutanthauza njira yogwirira ntchito ya laser. Mu CW mode, laser imatulutsa kuwala kokhazikika, mosiyana ndi ma pulsed laser omwe amatulutsa kuwala modzidzimutsa. Ma CW laser amagwiritsidwa ntchito pamene kuwala kopitilira komanso kokhazikika kukufunika, monga kudula, kuwotcherera, kapena kugwiritsa ntchito zojambula.

Kupopera kwa Diode:Mu ma laser opompedwa ndi diode, mphamvu yomwe imagwiritsidwa ntchito kusonkhezera laser imaperekedwa ndi ma semiconductor laser diode. Ma diode awa amatulutsa kuwala komwe kumayamwa ndi laser medium, kusangalatsa maatomu omwe ali mkati mwake ndikulola kuti atulutse kuwala kogwirizana. Kupompedwa kwa diode kumakhala kothandiza komanso kodalirika poyerekeza ndi njira zakale zopompera, monga ma flashlight, ndipo kumalola mapangidwe a laser ocheperako komanso olimba.

Laser Yolimba:Mawu akuti "solid-state" amatanthauza mtundu wa gain medium yomwe imagwiritsidwa ntchito mu laser. Mosiyana ndi ma laser a gasi kapena amadzimadzi, ma laser a solid-state amagwiritsa ntchito chinthu cholimba ngati medium. Medium iyi nthawi zambiri imakhala kristalo, monga Nd:YAG (Neodymium-doped Yttrium Aluminium Garnet) kapena Ruby, yokhala ndi zinthu zosadziwika bwino zomwe zimathandiza kupanga kuwala kwa laser. Kristalo wopangidwa ndi dope ndiye amene amakulitsa kuwala kuti apange kuwala kwa laser.

Ma Wavelengths ndi Mapulogalamu:Ma laser a DPSS amatha kutulutsa mphamvu zosiyanasiyana, kutengera mtundu wa zinthu zomwe zimagwiritsidwa ntchito mu kristalo ndi kapangidwe ka laser. Mwachitsanzo, kasinthidwe ka laser ya DPSS kamagwiritsa ntchito Nd:YAG ngati njira yopezera mphamvu kuti apange laser pa 1064 nm mu infrared spectrum. Mtundu uwu wa laser umagwiritsidwa ntchito kwambiri m'mafakitale podula, kuwotcherera, ndi kulemba zinthu zosiyanasiyana.

Ubwino:Ma laser a DPSS amadziwika ndi khalidwe lawo la kuwala kwamphamvu, kugwira ntchito bwino, komanso kudalirika. Amasunga mphamvu zambiri kuposa ma laser achikhalidwe olimba omwe amapopedwa ndi ma flashlight ndipo amapereka moyo wautali chifukwa cha kulimba kwa ma laser a diode. Amathanso kupanga ma laser okhazikika komanso olondola, omwe ndi ofunikira kwambiri pakugwiritsa ntchito mwatsatanetsatane komanso molondola kwambiri.

Kugwiritsa Ntchito Kwambiri kwa CW Diode Pumped Solid State Laser:

1.Kudula Daimondi kwa Laser:

Laser ya G2-A imagwiritsa ntchito njira yodziwika bwino yopangira kuwirikiza kawiri kwa ma frequency: kuwala kolowera kwa infrared pa 1064 nm kumasinthidwa kukhala mafunde obiriwira a 532-nm pamene kumadutsa mu kristalo wosakhala wa mzere. Njirayi, yomwe imadziwika kuti kuwirikiza kawiri kapena kupanga kwachiwiri kwa harmonic (SHG), ndi njira yodziwika kwambiri yopangira kuwala pa ma wavelength afupiafupi.

Mwa kuwirikiza kawiri kuchuluka kwa kuwala komwe kumachokera ku laser ya 1064-nm yokhala ndi neodymium kapena ytterbium, laser yathu ya G2-A imatha kupanga kuwala kobiriwira pa 532 nm. Njirayi ndi yofunika kwambiri popanga ma laser obiriwira, omwe amagwiritsidwa ntchito kwambiri kuyambira pa ma laser pointers mpaka zida zamakono zasayansi ndi mafakitale, komanso otchuka m'dera la Laser Diamond Cutting Area.

2. Kukonza Zinthu:

 Ma laser amenewa amagwiritsidwa ntchito kwambiri pokonza zinthu monga kudula, kuwotcherera, ndi kuboola zitsulo ndi zinthu zina. Kulondola kwawo kwakukulu kumawapangitsa kukhala abwino kwambiri popanga ndi kudula zinthu modabwitsa, makamaka m'mafakitale a magalimoto, ndege, ndi zamagetsi.

3. Ntchito Zachipatala:

Mu zamankhwala, ma laser a CW DPSS amagwiritsidwa ntchito pa opaleshoni yomwe imafuna kulondola kwambiri, monga opaleshoni ya maso (monga LASIK yowongolera maso) ndi njira zosiyanasiyana za mano. Kutha kwawo kulunjika minofu mwachindunji kumawathandiza kukhala ofunika kwambiri pa opaleshoni yosavulaza kwambiri.

4. Kafukufuku wa Sayansi:

Ma laser amenewa amagwiritsidwa ntchito m'njira zosiyanasiyana zasayansi, kuphatikizapo spectroscopy, particle image velocimetry (yomwe imagwiritsidwa ntchito mu fluid dynamics), ndi laser scanning microscopy. Kutuluka kwawo kokhazikika ndikofunikira pakuyeza molondola ndi kuwona mu kafukufuku.

5. Kulankhulana:

Mu gawo la kulumikizana kwa ma telecommunication, ma laser a DPSS amagwiritsidwa ntchito mumakina olumikizirana a fiber optic chifukwa cha kuthekera kwawo kupanga kuwala kokhazikika komanso kogwirizana, komwe ndikofunikira potumiza deta pamtunda wautali kudzera mu ulusi wa optical.

6. Kujambula ndi Kulemba kwa Laser:

Kulondola ndi kugwira ntchito bwino kwa ma laser a CW DPSS kumapangitsa kuti akhale oyenera kulemba ndi kulemba zinthu zosiyanasiyana, kuphatikizapo zitsulo, mapulasitiki, ndi zoumba. Amagwiritsidwa ntchito kwambiri popanga ma barcode, kulemba manambala, komanso kusintha zinthu kukhala zaumwini.

7. Chitetezo ndi Chitetezo:

Ma laser amenewa amapeza ntchito zodzitetezera pakupanga malo omwe akufuna, kupeza malo omwe alipo, komanso kuunika kwa infrared. Kudalirika kwawo komanso kulondola kwawo ndikofunikira kwambiri m'malo ovuta awa.

8. Kupanga Ma Semiconductor:

Mu makampani opanga ma semiconductor, ma laser a CW DPSS amagwiritsidwa ntchito pa ntchito monga lithography, annealing, ndi kuwunika ma semiconductor wafers. Kulondola kwa laser ndikofunikira popanga kapangidwe ka microscale pa ma semiconductor chips.

9. Zosangalatsa ndi Zowonetsera:

Amagwiritsidwanso ntchito mumakampani osangalatsa pa ziwonetsero za magetsi ndi zowonetsera, komwe kuthekera kwawo kupanga kuwala kowala komanso kolimba kumakhala kopindulitsa.

10. Ukadaulo wa Zamoyo:

Mu biotechnology, ma laser amenewa amagwiritsidwa ntchito pofufuza DNA ndi kusanthula maselo, komwe kulondola kwawo komanso mphamvu zomwe zimayendetsedwa ndizofunikira kwambiri.

11. Metrology:

Kuti muyeze molondola komanso mogwirizana ndi uinjiniya ndi zomangamanga, ma laser a CW DPSS amapereka kulondola kofunikira pa ntchito monga kuleza, kulumikizana, ndi kufotokoza.
