Phase control of a stimulated Brillouin scattering phase conjugate mirror by a self-generated density modulation

Conceptual design of the Kumgang laser: a high-power coherent beam combination laser using SC-SBS-PCMs towards a Dream laser

“…Since then, the results have improved and the method has been applied to four-beam coherent combination lasers with both the wavefront dividing method and the amplitude dividing method [23][24][25][26][27][28][29][30][31] . Figure 5 shows the experimental setup for verifying the principles of the SC-SBS-PCM [24] .…”

“…The feasibility of a beam combination laser using fluorocarbonate SBS-PCMs has been proved experimentally in the low power range of several W [23][24][25][26][27][28][29][30][31] . Currently we are working on experimental verification of this beam combination laser with an average output power in the kW range.…”

Stimulated Brillouin Scattering Phase Conjugate Mirror and its Application to Coherent Beam Combined Laser System Producing a High Energy, High Power, High Beam Quality, and High Repetition Rate Output

“…In the back-seeding beam method, the phase conjugation is incomplete if the injected Stokes beam is not completely correlated. Kong et al (2005aKong et al ( , 2005bKong et al ( , 2005c proposed a new phase control technique involving selfgenerated density modulation. In this method, which is simply called the self-phase control method, a simple optical composition is used with a single concave mirror behind the SBS cell; furthermore, each beam phase can be independently and easily controlled without destruction of the phase conjugation.…”

“…Therefore the phase controlling of the SBS wave is a key technology in the realization of a coherent beam combined system. For this reason, the self-phase control method was proposed and has been developed by Kong et al (2005aKong et al ( , 2005bKong et al ( , 2005c, which can control the phase of the SBS wave with the simplest composition as well as ease of alignment, no limitations on the number of combined beams, and excellent phase conjugation. Furthermore, the active phase control with a piezoelectric translator (PZT) enables long-term phase stabilization (Kong et al, 2006.…”

Stimulated Brillouin scattering phase conjugation of light beams carrying orbit angular momentum (Invited Paper)

“…Its specific properties have been widely studied and have been applied in many applications, such as phase conjugation [9,10] , pulse duration compression [11,12] , and line width compression [13] , even in the research for slow light [14] . Recently, the stimulated Brillouin amplification for vortex beams has been reported [15,16] .…”
