Abstract: | We report on to our knowledge the first time a diode-side-pumped simultaneous dual-wavelength Nd:YAG laser at 1116 and 1123 nm. By inserting an etalon to balance the gain and loss, a stable dual-wavelength oscillation is acquired. The numerical simulations for wavelength tuning are discussed by principles of laser threshold and Fabry-Perot etalon. Under the pump power of 250 W, a total output power of 23 W is obtained. Meanwhile, the two components have approximately equal intensities. The beam quality of M2 factor was measured to be 7.52. |
