Beam combined high energy/high power laser system operating at a repetition rate over 10Hz for laser fusion driver using stimulated Brillouin scattering phase conjugate mirrors

The authors developed a novel method for phase controlling of a stimulated Brillouin stimulated scattering wave (SBS wave) by a single concave mirror which is the most simple way ever found. The beam combination of small lasers using the SBS-phase conjugate mirrors enables the development of the unlimitedly high energy/high power laser operating at high repetition rate that is the same as the c...

Beam Combined Laser Fusion Driver using Stimulated Brillouin Scattering Phase Conjugation Mirrors

Beam combination method using stimulated Brillouin scattering phase conjugation mirrors (SBSPCMs) is a promising technique for the real laser fusion driver, which can be operated with a high repetition rate over 10 Hz. The phase control of the SBS wave is essential for realization of the coherent beam combined output. For this reason, we proposed a novel “self phase control technique” of the SB...

High Speed Delay-Locked Loop for Multiple Clock Phase Generation

In this paper, a high speed delay-locked loop (DLL) architecture ispresented which can be employed in high frequency applications. In order to design the new architecture, a new mixed structure is presented for phase detector (PD) and charge pump (CP) which canbe triggered by double edges of the input signals. In addition, the blind zone is removed due to the elimination of reset signal. Theref...

Multiple Channel Laser Beam Combination and Phasing Using Stimulated Brillouin Scattering in Optical Fibers

Brightness scaling lasers using stimulated Brillouin scattering (SBS) in optical fibers is explored. A multiple-channel amplifier approach is used to increase the total power of a laser system while avoiding a significant burden on a single channel. The work explores two approaches utilizing both SBS beam cleanup and SBS piston error conjugation. A unique beam combiner that takes advantage of t...
