- Abstract:
- Copper vapor Laser is one of the strongest and the most efficient visible laser with high repetition rate. It has been the subject of interest in research, industrial and clinical applications. It’s oscillating lines with 510.5 and 578.2 nm between resonance level and metastable level is acting as pulsed type laser. The problem with this laser is its high operating temperature of 1500 C. This high operating temperature could be reduced by using copper halides, where the temperature decreases from 400 to 500 C. The produced heat will first produce the molecular vapors, then the release and excitation of copper occurs with electrical discharge.
In the present study the effect of parameters such as applied voltage, pulse frequency, buffer gas pressure on the output voltage is investigated. A specific output power of 123 W/cm3 is obtained which is the same as reported world record. Ferthermore, with the band pass filter two main oscillating lines of this laser has been separated. The effect of applied voltage and frequency on the output power ratio of green to yellow has been investigated. The results show that the ratio of green to yellow transition power is reduced with power and frequency increase - Keywords:
