The output power and the temperature profile of a copper vapour laser were investigated versus frequency with various kinds of back mirror in its resonator cavity. A semi-experimental method was used for measuring the plasma temperature and obtaining the temperature profile with various back mirrors. The obtained plasma temperature through this method has good agreement with the operational temperature of the laser.

“…The notable point is that the oscillatory behaviour of the output power in terms of frequency is in agreement with our previous reports (Khorasani et al 2008;Zoghi et al 2009). This effect arises from the laser tube, which performs both as an optical and an acoustic resonator at some frequencies.…”

“…The maximum output power of ~1.6 W is obtained at 3.8 torr of air pressure and 17 kHz of frequency. The noticeable point is the oscillatory behavior of the output power in terms of the frequency, which is in agreement with the previous reports [41] [42]. The effect arises from the laser tube which performs both as an optical and an acoustic resonator at some frequencies.…”

In order to investigate the effect of the pressure buffer gas and frequency on the output power, a copper vapor laser with active medium length of 60 cm and bore of 16 mm has been operated and optimized using air as a buffer gas. The observed oscillatory behavior of the output power versus frequency is in good agreement with the previous reports. The measured results show the maximum output power of ~1.6W at the optimum pressure of 3.8 torr and frequency of 17 kHz. Abundance of the air and reduction of the system volume due to elimination of the gas handling system as well as the economically benefits are the advantages of the employing air as a buffer gas in the copper vapor laser operation.

“…As can be seen, the output power has fluctuations. The minima represent a significant output power drop attributed to the acoustic resonance of the laser tube (Zoghi, et al, 2009;khorasani et al, 2008). The acoustic wave changes the density of the medium in the vicinity of the resonator axis, and this leads to a change in the lasing condition.…”

In this work, an iodide copper vapor laser (CuI) has been designed and fabricated. The effect of different operational parameters such as frequency and buffer gas pressure on output power laser have been investigated to determine the optimal condition of frequency and neon gas pressure. Based on experimental results, the maximum output power of about 0.5W is obtained at 16 kHz of frequency and 30 torr of Ne gas pressure. Moreover the experimental results of CuI laser have been compared to the similar data for the other halide copper lasers such as CuBr and CuCl. The output power of CuI laser is less than that of others. The optimum frequency of lasers have different values, but the optimum gas pressures are the nearly same for three lasers, at the same conditions.
