1. Awọn ipilẹ ati Awọn anfani

Awọn lasers Femtosecond (iwọn pulse 10-15s) jẹ ki gbigba aiṣedeede ṣiṣẹ nipasẹ:

  • Iyọnu fọto pupọ (MPI)

  • ionization Avalanche (AI)
    Awọn anfani pataki:

  • Sunmọ-odo HAZ

  • Ipese-kere-kere (min. 1μm ihò)

  • Dara fun awọn ohun elo ti o ṣe afihan / sihin

2. Zero-HAZ Mechanisms

2.1 Agbara Gbigbe Iṣakoso

  • Electron-latice nonequilibrium

  • Alakoso bugbamu alakoso

  • Pilasima idabobo bomole

2.2 Awọn awoṣe Yiyọ Ohun elo

  • bugbamu Coulomb

  • Ti kii-gbona mnu fifọ

3. Lominu ni ilana paramita

Paramita Ibiti o Ilana
Igi gigun 343-1030nm Imudara gbigba
Agbara polusi 0.1-50μJ Iṣakoso ala ablation
