“…This homogenous line broadening is a consequence of the rapid decay time for the acoustic grating established by the high-intensity stimulated Brillouin scattering (SBS) pump beam. For the fluorinated hydrocarbon used in this work, known commercially as Fluorinert FC-75, the hypersound decay time is ϳ0.90 ns, corresponding to a measured spontaneous Brillouin scattering linewidth FWHM of 350 MHz [20]. While we have not studied the SBS line broadening in any detail, it is expected, due to line narrowing, that the additional linewidth imparted by the SBS process would be a fraction of the spontaneous Brillouin scattering linewidth [21].…”

We demonstrate the ability to generate ultra-high-frequency sequences of broadly wavelength-tunable, highintensity laser pulses using a custom-built optical parametric oscillator pumped by the thirdharmonic output of a "burst-mode" Nd:YAG laser. Burst sequences consisting of 6-10 pulses separated in time by 6-10 Îs are obtained, with average total conversion efficiency from the 355 nm pump to the near-IR signal and idler wavelengths of 33%. Typical individual pulse output energy for the signal and idler beams is in the range of 4-6 mJ, limited by the available pump energy. Line narrowing is demonstrated by means of injection seeding the idler wave using a low-power external-cavity diode laser at 827 nm. It is shown that seeding reduces the time-averaged linewidth of both the signal and idler outputs to 300 MHz, which is near the 220 MHz Fourier transform limit. Line narrowing is achieved without recourse to active cavity stabilization. RightsThis paper was published in Applied Optics and is made available as an electronic reprint with the permission of OSA.

“…In addition, SBS lowers the frequency of the phase conjugated wave as much as the sound wave frequency in accordance with the energy conservation. Yoshida et al, 1997). However, many SBS-PCM applications necessarily involve a broadband pumped SBS (transient region) because laser systems that use an SBS-PCM usually have a broadband spectrum to obtain high output power and short pulse widths (Dane et al, 1995;Králiková et al, 2000).…”

“…Thus, the linewidth of the multimode case is much larger than the Brillouin linewidth of the liquids used in this experiment, listed in Table 1. (Kmetik et al, 1998;Yoshida et al, 1997;Erokhin et al, 1986;Sutherland, 1996). The focal length of the lens used for the SBS-PCM is 15 cm.…”

In order to improve the optical limiting performance based on stimulated Brillouin scattering (SBS), a combination of SBS and carbon nanotube/HT-270 suspension for optical limiting is proposed in this paper. The dependence of output energy of optical limiting based on this hybrid approach on the pump energy is numerically simulated, and validated in Continuum's Nd: YAG seed-injected laser. The results indicate that the output energy based on this hybrid approach shows much better performance compared with that based on single SBS. In this approach, the SBS threshold can be controlled by adjusting the gain coefficient of medium and focal length of the lens, and the threshold of suspension can be controlled by altering the concentration and focal length of the lens, therefore, this hybrid approach to realize optical limiting has great potential in practical application.
