Abstract

We propose a continuous wave (CW) middle infrared (MIR) and long infrared (LIR) dual-band laser based on energy transferring from DF (v) to CO₂(00⁰0). A total output power of 5W is achieved by the proposed dual-band laser consisted of DF gain medium module (DF module) and DF-CO₂ gain medium module (DF-CO₂ module). Technologies about the gain peak position, beam qualification are analyzed. The two modules use a common stable resonator and output mirror with nominal transmissivities of 3.5%-5% in the MIR band and 6%-10% in the LIR band. Spectra of dual-band laser are acquired.
