The Mark-III Free Electron Laser (FEL), tuned to λ=6.45 μm has been demonstrated to provide for efficient ablation in ocular and neural tissues with minimal collateral damage. To date, the role of the FEL pulse structure on the mechanism of ablation has not been determined. In an effort to study the role of the FEL micropulse on the ablation of corneal tissue, the native pulse structure of the FEL, a 2.85 gigahertz repetition of picosecond pulses within a five microsecond macropulse envelope…

Analysis of soft tissue ablation using the pulse stretched free electron laser

TLDR
In this study, the native pulse structure of the FEL, a 2.85 gigahertz repetition of picosecond pulses within a five microsecond macropulse envelope, was changed using a pulse stretcher to reduce the peak intensity of the micropulse down to 1/200th of the original intensity, while the macrop Pulse energy remains unchanged.

Effect of micropulse duration on tissue ablation using a stretched free electron laser pulse train

The pulse train from a Mark III FEL tuned to a wavelength of 6.45 microns has been shown to be efficient at ablating soft tissue with minimal collateral damage. This laser has a unique pulse

Effect of FEL micropulse duration on ablation characteristics at 6.45 μm

TLDR
The role of the unique pulse structure of the Vanderbilt Mark-III FEL and its role in the efficient ablation of soft tissue with minimal collateral damage is examined and it is shown that the effect of micropulse duration of the FEL on the ablation process is negligible between 1 and 100 picoseconds.

Ablation of soft tissue at 6.45 μm using a strontium vapor laser

A gas discharge strontium vapor laser has been shown to operate with up to 90% of its light emitted at 6.45 μm. We have investigated the use of this laser as a potential stand-alone, tabletop

Free electron laser (FEL) laser-tissue interaction with human cornea and optic nerve

TLDR
It is concluded that different tissues may have different optimal wavelengths for surgical laser procedures, and the effect of selected infrared wavelengths upon human cornea and optic nerve tissues is investigated.

Delivery of midinfrared (6 to 7-microm) laser radiation in a liquid environment using infrared-transmitting optical fibers.

TLDR
It was shown that using the lambda = 6.45 microm wavelength delivered via fiber optics in combination with perfluorodecalin allows a noncontact laser surgical procedure, which may optimize the efficacy and safety of laser-based vitreoretinal surgery.

Fiber-delivered mid-infrared (6-7 μm) laser ablation of retinal tissue under perfluorodecalin

TLDR
Histological analysis of the retina in a limited number of eyes shows that retina ablation using this method is feasible and can be accomplished with minimal collateral damage.

Free-electron-laser-based biophysical and biomedical instrumentation

A survey of biophysical and biomedical applications of free-electron lasers (FELs) is presented. FELs are pulsed light sources, collectively operating from the microwave through the x-ray range. This

Tissue ablation by a free-electron laser tuned to the amide II band

TLDR
It is reported here that targeting free-electron laser radiation to the amide II band of proteins leads to tissue ablation characterized by minimal collateral damage while maintaining a substantial ablation rate.

Acute optic nerve sheath fenestration in humans using the free electron laser (FEL): a case report

TLDR
FEL energy at 6.45 micrometers can be transmitted to an operating room and delivered to human ocular tissue through a hollow waveguide surgical probe and this FEL wavelength can produce an optic nerve sheath fenestration without acute direct damage to the nerve in this case report.
