HIGH RESOLUTION LASER INDUCED FORWARD TRANSFER

In a method and system for laser induced forward transfer (LIFT), energy (E1,E2) is deposited according to a non-Gaussian intensity profile (Ixy) which is spatially tuned across an interface (11xy) of the donor material (11m) to cause the donor material (11m) to be ejected from the donor substrate a...

Summary:In a method and system for laser induced forward transfer (LIFT), energy (E1,E2) is deposited according to a non-Gaussian intensity profile (Ixy) which is spatially tuned across an interface (11xy) of the donor material (11m) to cause the donor material (11m) to be ejected from the donor substrate as an extended jet (Je) momentarily bridging the transfer distance (Zt) between the donor substrate (11) and the acceptor substrate (12) during a transfer period (Tt). A locally increased intensity spike (Is) at a center of the intensity profile (Ixy) causes a relatively thick jet (J1) of donor material to branch into a relatively thin jet (J2) at a branching position (J12) between the donor substrate (11) and acceptor substrate (12). The thick jet (J1) allows a relatively large transfer (Zt) distance while the thin jet (J2) deposits a relatively small droplet (Jd) of donor material (11m).
