WebMar 18, 2016 · The generation of dark pulse in the proposed cavity is based on dual-wavelength DW. Under the optimum polarization orientation, dark pulse was achieved … Webcircles on the light output vs. current curve presented in Fig. 2(b). The fact that the laser was operated in pulsed mode does not play a role in the optical measurements, because the repetition rate (500~800 kHz, current pulse width 125 ns for all measurements) was significantly higher than the tapping frequency of the AFM tip. WebThe fiber laser cavity had very small net birefringence, as reflected by the fact that the laser emission along the two orthogonal polarization directions of the cavity had a very small Fig. 5.
