Abstract
The present disclosure provides a method of an ultrafast-pulsed laser deposition and a device thereof, wherein a single emitted femtosecond pulse is split, and the split pulses are synchronized in the time domain, and then coupled with each other to form a plasma grating or lattice to excite the target material once; then multiple pulsed lasers are sequentially coupled multiple times with the plasma gratings or lattices to excite the target material multiple times, and the excited target material is deposited and reacted on the substrate to form a thin film.
Claims8
A method of an ultrafast-pulsed laser deposition, comprising:
- step 1:
- after splitting a femtosecond-pulsed laser beam, focalizing split femtosecond-pulsed laser beams to form a plasma channel based on a nonlinear effect and to generate a femtosecond laser filament;
- synchronizing the femtosecond-pulsed laser beam by delay synchronization processing so as to form a plasma grating or a plasma lattice by the femtosecond laser filament coupled with each other non-collinearly and crossly;
- and exciting a target material with the plasma grating or the plasma lattice;
- step 2:
- emitting multiple ultrafast-pulsed laser beams as post pulses;
- coupling the post pulses with the plasma grating or the plasma lattice sequentially, by controlling a first delay between the post pulses and the plasma grating or the plasma lattice and a second delay between the post pulses thereof, so as to form a regenerated plasma grating or a regenerated plasma lattice with multi-stage cascade in a time domain;
- and exciting the target material for multiple times;
- and
- step 3:
- exciting and ablating the target material by adjusting the ultrafast-pulsed laser beams coupled with the regenerated plasma grating or the regenerated plasma lattice, to form a thin film with a required thickness by a deposition of ablated particles on a substrate, by controlling the time.
