摘要
A novel and inexpensive excitation circuit based on a single switch and a single source drives helium-free TEA CO2 lasers, mini to conventional types, providing low divergent output. By varying the partial pressure of either CO2 or N2, the duration (FWHM) and the peak power of the laser pulse (for a system with active volume about 70 cc) is made to vary by a factor of about 7 and about 5 respectively. The fact that expensive and scarce helium is not a constituent of the laser gas mixture makes it an ideal system for high repetition rate operation as the gas re-circulatory loop consisting of the heat exchanger and the catalytic re-converter, a mandatory requirement for conventional systems to recycle helium gas, can be readily dispensed with here. This laser can be used wherever a TEA CO2 laser with conventional gas mixture containing helium is used.
