摘要：
Based on the kinetic model of diode-pumped alkali vapor lasers, operation parameters including helium pressure, temperature and output mirror reflectivity are optimized for hydrocarbon free Rb laser and K laser. A comparative study on the output characteristics of hydrocarbon free Rb laser and K laser is also carried out. Results show that a better capability is presented in hydrocarbon free K laser instead of hydrocarbon free Rb laser, such as lower pump threshold, higher laser gain and optical-to-optical efficiency. The performance difference between K and Rb laser is mainly induced by the difference of helium pressure, which results in an evident difference on the absorption cross section and emission cross section.
