The CO2 laser in pediatric surgery

Journal of Pediatric Surgery, 1984
The CO2 laser has found its place in surgery and is now an accepted modality in many fields. Its application in pediatric surgery is well based and it is our opinion that its use in this field should be more widespread.

A CO2 laser for surgical research

Medical & Biological Engineering, 1970
The characteristics of CO2 lasers that render them interesting for surgical applications are reviewed. An instrument consisting of an integrated CO2 laser and beam manipulator, designed specifically for surgical research work, is descirbed. Operational characteristics of the instrument relevant to such work are reported.

The CO2 laser in oculoplastic surgery

Survey of Ophthalmology, 1997
The introduction of a new generation of carbon dioxide (CO2) lasers has permitted the development of new approaches toward certain oculoplastic disorders and procedures. The high absorption of this infrared laser by tissue water assists oculoplastic surgeons in performing incisional and excisional procedures precisely and with relatively good ...

Phase conjugation with CO2 lasers

Infrared Physics & Technology, 1995
A TEA CO2 laser was used for the investigation of four-wave mixing (4WM) processes in sulfur hexafluoride (SF6), an organic solvent (toluene), and III/V semiconductor wafers (InSb, InAs). The relevant involved grating mechanisms were probed by the 4WM technique.

CO2 laser dynamics with feedback.

Physical review. A, Atomic, molecular, and optical physics, 1995
The validity of the four-level model is controlled in an experiment with a CO2 laser with electronic feedback. A global application of center manifold theory allows one to reduce the number of varieties from six to four. Qualitative differences are found with the case of loss modulations.

Longitudinally Excited CO2 Laser with Short Laser Pulse like TEA CO2 Laser

Journal of Infrared, Millimeter, and Terahertz Waves, 2009
We have developed a longitudinally excited CO2 laser with a short laser pulse similar to that of TEA and Q-switched CO2 lasers. A capacitor transfer circuit with a low shunt resistance provided rapid discharge and a sharp spike pulse with a short pulse tail.

Laser Osteotomy with Pulsed CO2 Lasers

2007
Non-contact laser osteotomy offers new opportunities in various surgical fields, since it allows very precise pre-programmed incisions with completely free geometry. However laser osteotomy is a demanding task, because bone is a tough composite material, which is at the same time a living tissue and sensitive to temperature increases.
