“…34,35) On the other hand, the pump-induced gain anisotropy could manifest itself in the dependence of the lasing thresholds and the polarization mode intensities on the pump polarization orientation. 36,37) Therefore, pump polarization offers another degree of freedom for controlling the lasing characteristics of miniature waveguide lasers.…”

A multi-wavelength compact ultrafast laser based on a single-mode waveguide inscribed in Nd:YAG and graphene saturable absorber is developed. By changing the pump parameters, we demonstrate single-, dual-and multi-wavelength mode-locking regimes. Accurate control of intracavity losses provides stable CW passive mode-locking at a wavelength of 1064 nm and dual-wavelength mode-locking at 1061 and 1064 nm with a pulse repetition rate of 9.5 GHz.

“…The polarization directions of these two components coincide with the principal stress directions respectively, and the frequency difference between them is proportional to the difference between the magnitudes of two principle stresses. In addition, the power ratio of two components can be adjusted by changing the pump polarization direction so as to get the higher laser energy utilization in the heterodyne interferometry [15].…”

In the laser heterodyne interferometry based on the microchip Nd:YAG dual-frequency laser, the amplitude of the beat note periodically fluctuates in time domain, which leads to the instability of the measurement. On the frequency spectrums of the two mono-frequency components of the laser and their beat note, several weak sideband signals are observed on both sides of the beat note. It is proved that the sideband frequencies are associated with the relaxation oscillation frequencies of the laser. The mechanism for the relaxation oscillations inducing the occurrence of the sideband signals is theoretically analyzed, and the quantitative relationship between the intensity ratio of the beat note to the sideband signal and the level of the amplitude fluctuation is simulated with the derived mathematical model. The results demonstrate that the periodical amplitude fluctuation of the beat note is actually induced by the relaxation oscillation. And the level of the amplitude fluctuation is lower than 10% when the intensity ratio is greater than 32 dB. These conclusions are beneficial to reduce the amplitude fluctuation of the microchip Nd:YAG dual-frequency laser and improve the stability of the heterodyne interferometry.

“…In order to achieve the absolute-distance measurement accuracy to an order greater than 10 −6 , the frequency-difference stability of the dual-frequency solid-state laser must be an order of 10 −7 or better. Therefore, the frequency-difference-stabilized dual-frequency solid-state laser with tunable and large frequency difference can be used as an ideal light source for the synthetic-wave absolute-distance interferometric system [ 10 , 11 , 12 , 13 ].…”

Frequency-difference-stabilized dual-frequency solid-state lasers with tunable and large frequency difference have become an ideal light source for the high-accuracy absolute-distance interferometric system due to their stable multistage synthetic wavelengths. In this work, the advances in research on oscillation principles and key technologies of the different kinds of dual-frequency solid-state lasers are reviewed, including birefringent dual-frequency solid-state lasers, biaxial and two-cavity dual-frequency solid-state lasers. The system composition, operating principle, and some main experimental results are briefly introduced. Several typical frequency-difference stabilizing systems for dual-frequency solid-state lasers are introduced and analyzed. The main development trends of research on dual-frequency solid-state lasers are predicted.
