Manyan Masana'antu da Ci gaban Masana'antu

Yawancin masana'antun duniya sun mamaye masana'antar laser ultrafast:

1. Haɗin kai, Spectra-Physics, Newport (MKS) - Kafa kamfanoni tare da balagagge fasaha da fadi da kewayon masana'antu da aikace-aikace na kimiyya.

2. TRUMPF, IPG Photonics – Market shugabannin a masana'antu Laser aiki mafita.

3. Masanan Sinanci (Laser Han, GaussLasers, YSL Photonics) - 'Yan wasa masu tasowa suna samun ci gaba mai mahimmanci a cikin tsarin laser, fasahar kulle yanayin, da haɗin tsarin.

Tsare-tsare na sanyaya da Kula da thermal

Duk da ƙarancin matsakaicin ƙarfinsu, lasers na ultrafast suna haifar da babban zafi nan take saboda babban ƙarfinsu. Ingantattun tsarin sanyaya suna da mahimmanci don tabbatar da ingantaccen aiki da tsawon rayuwar aiki.

Chiller Systems: Laser Ultrafast yawanci sanye take da masana'antu chillers tare da madaidaicin sarrafa zafin jiki na ± 0.1 ° C ko mafi kyau don kula da ingantaccen aikin laser.

TEYU CWUP-jerin Chillers : An ƙera shi musamman don sanyaya Laser ultrafast, waɗannan chillers na Laser suna ba da ka'idojin zafin jiki mai sarrafa PID tare da madaidaicin girman 0.08 ° C zuwa 0.1 ° C. Hakanan suna goyan bayan sadarwar RS485 don saka idanu mai nisa da sarrafawa, yana mai da su manufa don tsarin laser 3W -60W ultrafast.

Yanayin gaba a cikin Ultrafast Lasers

The ultrafast Laser masana'antu ne tasowa zuwa ga:

1. Gajeren bugun jini, Maɗaukakin Ƙarfi: Ci gaba da ci gaba a cikin yanayin kulle-kulle da matsawa bugun jini zai ba da damar laser bugun bugun jini na attosecond don aikace-aikacen daidaici.

2. Modular and Compact Systems: Laser ultrafast na gaba za su kasance da haɗin kai da abokantaka mai amfani, rage rikitarwa da farashin aikace-aikacen.

3. Ƙananan Farashi da Matsala: Kamar yadda manyan abubuwan da aka gyara kamar lu'ulu'u na Laser, tushen famfo, da tsarin sanyaya suka zama cikin gida ana samarwa, farashin Laser na ultrafast zai ragu, yana sauƙaƙe ɗaukar nauyi.

4. Haɗin Kai-Industry: Laser Ultrafast za su ƙara haɗuwa tare da filayen kamar sadarwa na gani, bayanan ƙididdiga, mashin ɗin daidaitaccen aiki, da binciken ilimin halittu, tuki sabbin sabbin fasahohi.

Kammalawa

Fasahar Laser Ultrafast tana ci gaba da sauri, tana ba da daidaitattun daidaito da ƙarancin tasirin zafi a fagagen masana'antu, likitanci, da kimiyya. Manyan masana'antun suna ci gaba da haɓaka sigogin laser da dabarun haɗin kai yayin da ci gaba a cikin tsarin sanyaya da tsarin kula da thermal yana haɓaka kwanciyar hankali na Laser. Yayin da farashin ke raguwa kuma aikace-aikacen masana'antu ke fadada, ana saita laser ultrafast don sauya masana'antu masu fasaha da yawa.
