“…Without the aperture and the F−P etalon, the laser operated in CW mode could reach 560 mW with the incident pump power of 10.7 W, as shown in Figure 5a. This value is lower than our previous work [59], mainly because we used a longer cavity and an output coupling mirror with higher transmittance. The laser spectra were measured using a Fourier transform optical spectrum analyzer (Thorlabs, OSA207C, Newton, NJ, USA), as shown in the insert of Figure 5.…”

We present a mode−locked GaSb−based optically pumped semiconductor disk laser operating at 2 µm based on the self−mode−locked mechanism. Using the delay differential equation model, we discuss the influence of cavity length on the stability of self−mode−locking and design a Z−shaped long cavity for self−mode−locking. Employing an aperture and an F−P etalon in the cavity length of ~365 mm, we obtain stable self−mode−locking at a center wavelength of 2034.5 nm, with a pulse duration of 255.48 ps and average output power of 173 mW at a repetition rate of 404 MHz.

“…Benefiting from high quality (Q) factor and small mode volume, whispering-gallery-mode (WGM) microcavities have attracted considerable interest in both fundamental physics research and practical device applications, such as microlasers and optical filters. [1][2][3][4][5][6][7] Among the WGM microcavities with various shapes, including microspheres, [8][9][10][11] microdisks, [12][13][14] microtoroids, [15,16] and microrings, [17,18] symmetric circular microresonators have been demonstrated successfully for ultralow-threshold microlasers, due to their ultrahigh quality WGMs. [19,20] However, the disadvantage of these WGM microcavity structures is their in-plane isotropy resulting in extremely low efficiency of collection in free space.…”

We demonstrate the curvature of coupled twin circular-side-octagon microcavity (TCOM) lasers as the degree of freedom to realize manipulation of mode quality (Q) factor and lasing characteristics. Numerical simulation results indicate that mode Q factors varying from 104 to 108, wavelength intervals of different transverse modes, and mode numbers for four-bounce modes can be manipulated for five different deformations. Global mode distributes throughout coupled microcavity with mode Q factor around the order of 104 or 105. Four-bounce modes lase with injection currents applied single microcavity. By pumping both microcavities simultaneously, single-mode lasing for global modes with side mode suppression ratios (SMSRs) of 30, 32, 32, 31, and 36 dB is achieved at the deformation of 0, 0.5, 1, 1.5, and 2 with four-bounce modes suppressed, respectively. Moreover, the linewidths less than 11 MHz for the single mode are obtained with the deformation of 2. The results show that the lasing modes can be efficiently manipulated considering variable curvature for TCOM lasers, which can promote practical applications of microcavity lasers.
