“…Multiwavelength generation can occur if the round-trip gain in the laser cavity, which determines the pump threshold condition for several spectral components is identical. Dualwavelength lasers usually utilize specially designed dichroic output couplers and/or a spectrally selective Brewster plate, a phase plate, a Lio filter, or a Fabri-Perot etalon [16][17][18][19][20][21][22][27][28][29]. By varying the reflectivity of the output coupler and fine alignment of spectrally selective elements, it is possible to introduce active, passive or polarization losses at the certain wavelength and, thus, equalize the gain in the laser cavity.…”

“…By varying the reflectivity of the output coupler and fine alignment of spectrally selective elements, it is possible to introduce active, passive or polarization losses at the certain wavelength and, thus, equalize the gain in the laser cavity. Wang et al described the simultaneous triple-wavelength laser at 1323, 1331, and 1336 nm based on a longitudinally diode-pumped Nd:GGG laser with an intracavity 0.1 mm thick BK7 glass etalon [29].…”

Dual- and triple-wavelength diode-side-pumped electro-optically Q-switched Nd:YAG laser at 1318.8 nm, 1338.2 nm and 1356.4 nm with an intracavity etalon was demonstrated. The spectral composition of the generation was controlled by the rotation of the intracavity YAG etalon with a thickness of 100 µm. The experimental values of the tilt angle of the etalon for the laser generation with dual- and triple-wavelength output correspond well to the calculated values. When pumped by the electrical pulses with an energy of 8.7 J, triple-wavelength laser pulses with an energy of 96 mJ, a pulse duration of 37 ns, a peak power up to 2.6 MW and a repetition rate of 100 Hz were obtained. The proposed method of using an intracavity etalon allows to switch the spectral composition of the output radiation of Nd:YAG laser at 4F3/2 → 4I13/2 transition between single-, dual- and triple-wavelength modes.
