“…If two laser rods positioned with a distance d close enougth so that d<<fmax and d<<fmin, (resonator scheme shown in Fig. 6), then similar equations are obtained [12,19]: From these equations we can note the design advantages of this kind of resonators: first, they are easy design equations, which directly link stability parameters with physical resonator parameters. Second, for a given stability parameters, there is no need to have a mirror or a lens with a specific focusing length.…”

“…The limit of the stability interval at maximum focal distance is fmax and the width of the stability zone is termed as ∆f=fmax-fmin. For a resonator with this geometry, the limits of the stability interval are given by [12,19]:…”

“…The following stability zone parameters can be utilized from previous work with two modules [12,[19][20][21]: fmax=278.1 mm and Δf=68.1 mm. In this resonator, the 500 mm curvature radius mirror was chosen because it allowed the near normal incidence angle at the curved mirrors and also avoiding the laser beam blocking by the laser modules.…”

When considering dynamically stable resonators, ring lasers are good choices because they have a twice larger stability interval when compared to linear resonators and sensitivity to misalignment decreasing with pump power, however literature does not provide easy design guidelines. A ring resonator utilizing Nd:YAG side pumped by diodes allowed single frequency operation. The output single-frequency laser had good output characteristics, however the overall length of resonator did not allow for building a compact device with low misalignment sensitivity and larger spacing between longitudinal modes which could improve single-frequency performance. Based on previously developed equations, which allow for ease of design of a ring DSR, we discuss how to build an equivalent ring resonator, aiming to building a shorter resonator with the same stability zone parameters. The study of the symmetric resonator containing a pair of lenses allowed finding the conditions to build the shortest possible resonator.

“…For instance, Yang et al [36] reported an 8 W diamond Raman CW laser that is continuously tunable across the range from 590 nm to 625 nm. Besides that, Bereczki et al [37] presented a Nd:YAG rod single-frequency ring laser in a dynamically stable resonator providing 55.6 W of continuous, linearly polarized, TEM 00 output. Depending on the nonlinear loss, the intracavity linear loss was precisely measured by recording the powers of the fundamental-wave and second-harmonic-wave lasers.…”

High-power all-solid-state single-frequency continuous-wave (CW) lasers have been applied in basic research such as atomic physics, precision measurement, radar and laser guidance, as well as defense and military fields owing to their intrinsic advantages of high beam quality, low noise, narrow linewidth, and high coherence. With the rapid developments of sciences and technologies, the traditional single-frequency lasers cannot meet the development needs of emerging science and technology such as quantum technology, quantum measurement and quantum optics. After long-term efforts and technical research, a novel theory and technology was proposed and developed for improving the whole performance of high-power all-solid-state single-frequency CW lasers, which was implemented by actively introducing a nonlinear optical loss and controlling the stimulated emission rate (SER) in the laser resonator. As a result, the output power, power and frequency stabilities, tuning range and intensity noise of the single-frequency lasers were effectively enhanced.

“…For maximum performance of resonators, fine tuning of the dynamic working point is required, and the possibility of performing this tuning was demonstrated for linear resonators with joined stability zones [5], asymmetric flat-flat mirrors [11] and symmetric ring lasers with a pair of curved mirrors [12].…”
