Output Spectral Characteristics of Discharge Initiated Non-Chain Pulsed HF Laser
The laser output spectral characteristics are measured and studied with the discharge initiated pulsed HF laser developed by our project team. The results show that the spectral energy of the discharge initiated pulsed HF laser is mainly concentrated in three vibrational transition bands of v(3—2), v(2—1) and v(1—0). The 13-16 main output spectral lines are obtained by the measurements in the wavelength range of 2.65-3.05 μm, in which the v(2—1) vibrational transition band has the highest output energy ratio, about 40%-50%. The output energy ratio in each vibrational transition band can be tuned via the suitable adjustment of charging voltage and total working gas pressure. The output energy ratio in the v3 vibrational transition band increases with the increase of laser charging voltage, but decreases with the increase of total working gas pressure, which is opposite to those for the v1 vibrational transition band.
