The frequency dependence of the dissociation rate of the 0~04 molecule by a strong infrared resonant field is shown to have a rich structure due to multiple photon absorption resonances. This permits laser isotope separation with small isotope shift. No dissociation was observed in the case of excit

β¦ Synopsis
The visl%le luminescence resulting from multiple-photon absorption of CO, laser radzation in 0504 depends upon the laser intensity as well as fluenco. The use of single-mode laser pulses, shaped by electro-optic crystal switching, has enabled this intensity dependence to be determined quantitatively.

## Abstract ## Objective To determine whether laser light can improve healing of skin wounds by killing wound bacteria while simultaneously accelerating host tissue activity. ## Materials and Methods Wounds on the rat dorsum were irradiated or shamβirradiated three times weekly from days 1 to 19
SiH, absorption of 10 pm laser radialion from a continuously [unable COz laser has been measured. The occurrence of mulGple-pholon excitarion has been shown from comparison wirh linear absorplion spectra and from the dependence of some peak inlensiries upon laser fluence.
