Faɗin Pulse na Lasers masu Pulse

Faɗin bugun jini yana nufin tsawon lokacin bugun jini, kuma kewayon yawanci yana farawa daga nanoseconds (ns, 10)^-9daƙiƙa) zuwa femtoseconds (fs, 10^-15daƙiƙa). Na'urorin laser masu bugun jini daban-daban sun dace da aikace-aikace daban-daban:

- Gajeren Faɗin Bugawa (Picosecond/Femtosecond):

Ya dace da sarrafa kayan da suka lalace (misali, gilashi, saffir) don rage tsagewa.

- Faɗin Bugawa Mai Dogon Tsayi (Nanosecond): Ya dace da yanke ƙarfe, walda, da sauran aikace-aikace inda ake buƙatar tasirin zafi.

- Femtosecond Laser: Ana amfani da shi a tiyatar ido (kamar LASIK) domin yana iya yin yanke-yanke daidai ba tare da lahani ga kyallen da ke kewaye ba.

- Ƙwayoyin Haɗaka Masu Gajeruwa: Ana amfani da su don nazarin hanyoyin aiki masu sauri, kamar girgizar ƙwayoyin halitta da halayen sinadarai.

Faɗin bugun jini yana shafar aikin laser, kamar ƙarfin kololuwa (P)_ƙololuwa= kuzarin bugun jini/faɗin bugun jini. Da zarar ya yi guntu, haka nan ƙarfin kololuwar ƙarfin bugun jini ɗaya ya fi girma.) Hakanan yana tasiri ga tasirin zafi: faɗin bugun jini mai tsawo, kamar nanoseconds, na iya haifar da tarin zafi a cikin kayan aiki, wanda ke haifar da narkewa ko lalacewar zafi; faɗin bugun jini mai gajeru, kamar picoseconds ko femtoseconds, yana ba da damar "sarrafa sanyi" tare da raguwar yankunan da zafi ke shafa.

Laser ɗin fiber yawanci suna sarrafa da daidaita faɗin bugun jini ta amfani da dabarun da ke ƙasa:

1. Sauyawar Q-Switching: Yana haifar da bugun nanosecond ta hanyar canza asarar resonator lokaci-lokaci don samar da bugun mai ƙarfi.

2. Yanayin kullewa: Yana haifar da bugun picosecond ko femtosecond ultrashort ta hanyar daidaita yanayin tsayi a cikin resonator.

3. Masu daidaita sauti ko Tasirin da ba na layi ba: Misali, amfani da Juyawan Rarraba ...
