Za ku iya bambance tsakanin laser nanosecond, laser picosecond da laser femtosecond?

Da farko, bari mu fahimci ma'anar waɗannan "na biyu".

Nanosecond 1 = 10^-9 daƙiƙa

1 picosecond = 10^-12 daƙiƙa

1 femtosecond = 10^-15 daƙiƙa

Saboda haka, babban bambanci tsakanin nanosecond laser, picosecond laser da femtosecond laser yana cikin tsawon lokacin su.

Ma'anar utlrafast laser

Tun da daɗewa, mutane sun yi ƙoƙarin amfani da laser don yin micromachining. Duk da haka, tunda laser na gargajiya yana da faɗin bugun jini mai tsawo da ƙarancin ƙarfin laser, kayan da za a sarrafa suna da sauƙin narkewa kuma suna ci gaba da ƙafewa. Duk da cewa ana iya mayar da hasken laser zuwa ƙaramin wurin laser, tasirin zafi ga kayan har yanzu yana da girma sosai, wanda ke iyakance daidaiton aikin. Rage tasirin zafi ne kawai zai iya inganta ingancin aikin.

Amma lokacin da laser mai sauri yana aiki akan kayan, tasirin sarrafawa yana da babban canji. Yayin da kuzarin bugun jini ke ƙaruwa sosai, yawan ƙarfin yana da ƙarfi sosai don cire kayan lantarki na waje. Tunda hulɗar da ke tsakanin laser mai sauri da kayan ta yi gajeru, an riga an cire ion ɗin a saman kayan kafin ya isar da makamashin ga kayan da ke kewaye, don haka ba za a kawo tasirin zafi ga kayan da ke kewaye ba. Saboda haka, sarrafa laser mai sauri kuma ana kiransa da sarrafa sanyi.

Akwai nau'ikan aikace-aikacen laser mai sauri iri-iri a masana'antu. A ƙasa za mu ambaci kaɗan:

1. Haƙa rami

A tsarin allon da'ira, mutane suna fara amfani da harsashin yumbu don maye gurbin harsashin filastik na gargajiya don samun ingantaccen ikon sarrafa zafi. Domin haɗa sassan lantarki, ana buƙatar haƙa ƙananan ramuka na matakin μm a kan allon. Saboda haka, don kiyaye harsashin ya tsaya cak ba tare da an tsoma shi da zafi ba yayin haƙa rami ya zama mahimmanci. Kuma picosecond lase shine kayan aiki mafi kyau.

Laser na Picosecond yana gano haƙa rami ta hanyar bugun bututu kuma yana kiyaye daidaiton ramin. Baya ga allon da'ira, laser na picosecond kuma ana amfani da shi don yin haƙa rami mai inganci akan fim ɗin filastik mai siriri, semiconductor, fim ɗin ƙarfe da sapphire.

2. Rubutu da yankewa

Ana iya ƙirƙirar layi ta hanyar ci gaba da duba don rufe bugun laser. Wannan yana buƙatar yin bincike mai yawa domin zurfafa cikin yumbu har sai layin ya kai kashi 1/6 na kauri na kayan. Sannan a raba kowane ɗayan sassan daga tushe na yumbu tare da waɗannan layukan. Ana kiran wannan nau'in rabawa rubutu.

Wata hanyar rabawa ita ce yankewar bugun jini ta hanyar laser. Yana buƙatar a cire kayan har sai an yanke kayan gaba ɗaya.

Ga rubutun da yankewa da ke sama, laser picosecond da laser nanosecond sune zaɓuɓɓuka mafi kyau.

3. Cire murfin

Wani amfani da na'urar sarrafa laser mai sauri shine cire murfin. Wannan yana nufin cire murfin daidai ba tare da lalata ko lalata kayan tushe ba. Ragewar na iya zama layuka masu faɗin micrometer da yawa ko kuma manyan sikelin murabba'in santimita da yawa. Tunda faɗin murfin ya fi ƙanƙanta fiye da faɗin rabewar, zafin ba zai canza zuwa gefe ba. Wannan ya sa nanosecond laser ya dace sosai.

Laser mai sauri yana da babban ƙarfin aiki da kuma kyakkyawar makoma. Ba ya buƙatar gyara bayan aiki, sauƙin haɗawa, ingantaccen aiki, ƙarancin amfani da kayan aiki, ƙarancin gurɓataccen muhalli. An yi amfani da shi sosai a cikin motoci, kayan lantarki, kayan aiki, kera injuna, da sauransu. Domin ci gaba da aiki da laser mai sauri a cikin dogon lokaci, dole ne a kula da zafinsa sosai. Jerin na'urorin sanyaya ruwa na Teyu CWUP sun dace sosai don sanyaya laser mai sauri har zuwa 30W. Waɗannan na'urorin sanyaya laser suna da babban matakin daidaito na ±0.1℃ kuma suna tallafawa aikin sadarwa na Modbus 485. Tare da bututun da aka tsara yadda ya kamata, damar samar da kumfa ta zama siriri sosai, wanda ke rage tasirin laser mai sauri.
