Kodi laser yagalasi ya Erbium ndi chiyani?

Laser yagalasi ya erbium ndi gwero la laser lothandiza lomwe limagwiritsa ntchito ma erbium ions (Er³⁺) omwe ali mugalasi ngati njira yopezera mphamvu. Mtundu uwu wa laser umagwiritsidwa ntchito kwambiri pa ma wavelength apafupi ndi infrared, makamaka pakati pa 1530-1565 nanometers, zomwe ndizofunikira kwambiri pa kulumikizana kwa fiber optic, chifukwa ma wavelength ake amafanana ndi mawonekedwe a transmission a fiber optics, zomwe zimapangitsa kuti mtunda ndi ubwino wa transmission ya chizindikiro zipitirire.

Mfundo Yogwirira Ntchito

1. Gain Medium: Pakatikati pa laser ndi galasi lopangidwa ndi ma erbium ions, omwe nthawi zambiri amakhala galasi la Yb lopangidwa ndi erbium kapena galasi la quartz lopangidwa ndi erbium. Ma erbium ions awa amagwira ntchito ngati gain medium mu laser.

2. Gwero la Kutulutsa Mphamvu: Ma ion a erbium amatulutsidwa ndi gwero la kuwala kwa pampu, monga nyali ya xenon kapena laser ya diode yogwira ntchito bwino kwambiri, zomwe zimasinthira ku mkhalidwe wosangalatsa. Kutalika kwa kutalika kwa gwero la pampu kuyenera kufanana ndi mawonekedwe a kuyamwa kwa ma ion a erbium kuti akwaniritse kutsitsimuka koyenera.

3. Kutulutsa kwadzidzidzi ndi kolimbikitsidwa: Ma ion a erbium olimbikitsidwa amatulutsa ma photon okha, omwe angagundane ndi ma ion ena a erbium, zomwe zimayambitsa kutulutsa kwamphamvu ndikuwonjezera mphamvu ya kuwala. Njirayi imabwerezabwereza mosalekeza, zomwe zimapangitsa kuti laser ikule.

4. Kutulutsa kwa Laser: Kudzera m'magalasi omwe ali kumapeto onse a laser, kuwala kwina kumabwereranso ku gain medium, zomwe zimapangitsa kuti kuwala kuwoneke bwino ndipo pamapeto pake kumatulutsa kuwala kwa laser pamlingo winawake.

Zinthu Zofunika Kwambiri

1. Kutalika kwa mafunde: Kutalika kwa mafunde oyambira kuli pakati pa ma nanometer 1530-1565, zomwe ndizofunikira kwambiri pa kutumiza deta bwino mu kulumikizana kwa fiber optic.
2. Kugwira Ntchito Mwachangu pa Kusintha: Ma laser agalasi a Erbium ali ndi mphamvu zambiri pakusintha kuwala kwa pampu, zomwe zimapereka mphamvu zabwino pakugwiritsa ntchito mphamvu zosiyanasiyana.
3. Kupeza Broadband: Amakhala ndi bandwidth yochuluka yopezera mphamvu, zomwe zimapangitsa kuti akhale oyenera kugwiritsa ntchito zizindikiro zambiri za kutalika kwa nthawi imodzi kuti akwaniritse zofunikira zamakono zolumikizirana.

Mapulogalamu

1. Kulankhulana kwa Fiber Optic: Mu machitidwe olumikizirana, ma laser agalasi a erbium amagwiritsidwa ntchito pokulitsa ndi kukonzanso zizindikiro, zomwe zimathandizira kwambiri mtunda wotumizira ndi khalidwe, makamaka m'maukonde a fiber akutali.
2. Kukonza Zinthu: Ma laser agalasi a erbium amagwiritsidwa ntchito kwambiri m'mafakitale monga kudula, kuwotcherera, ndi kujambula, chifukwa cha mphamvu zawo zambiri.
3. Zachipatala: Mu gawo la zamankhwala, ma laser agalasi a erbium amagwiritsidwa ntchito pochiza matenda osiyanasiyana a laser, monga mavuto a khungu ndi opaleshoni ya maso, chifukwa cha makhalidwe awo abwino kwambiri oyamwa m'mafunde enaake a minofu ya zamoyo.
4. Lidar: Mu machitidwe ena a lidar, ma laser agalasi a erbium amagwiritsidwa ntchito pozindikira ndi kuyeza, kupereka chithandizo cholondola cha deta yoyendetsera yokha komanso mapu a malo.

Ponseponse, ma laser agalasi a erbium amasonyeza kuthekera kwakukulu kogwiritsa ntchito m'magawo osiyanasiyana chifukwa cha magwiridwe antchito awo ogwira ntchito bwino komanso odalirika.
