“…Apart from AOTFs, LBS can be obtained with the help of programmable acousto-optic modulators and deflectors. A number of AO systems have been proposed for the design of laser-based displays and image projectors [26][27][28][29]. Antonov et al [30,31] studied multi-beam diffraction of a laser beam in a single Bragg cell both theoretically and experimentally and demonstrated precisely controllable splitting of a single beam into five output beams.…”

We present analysis and numerical simulations of the acousto-optic spatial filter (AOSF) transfer function under the condition of dual-transducer operation and phase control. Based on these simulations, the AOSF crystal configuration is optimized for operation in the near-infrared wavelength region from 0.7 to 1.0 μm. We demonstrate that ultrasonic phase control can provide efficient tuning of the transfer function, which is independent of conventional frequency control. Thus, the application of phase control coupled with frequency control can reduce the transfer function asymmetry that is inherent to anisotropic Bragg diffraction in uniaxial crystals.

“…1,2 Its brilliance and large depth of focus make a laser projection display an ideal projector in many ways. The red-green-blue fundamental laser output needed for a full-color laser image can be produced by frequency-converted near-infrared, diode-pumped solid-state lasers, as the narrow linewidth can effectively avoid the walk-off effect and the high peak power would improve conversion efficiency in the process of nonlinear frequency conversion.…”

Abstract. We report a compact, 130-W single-stage master oscillator power amplifier with a high peak power of 51.3 kW and a narrow spectral linewidth of 0.1 nm. The seed source is a single-mode, passively mode-locked solid-state laser at 1064 nm with an average power of 2 W. At a repetition rate of 73.5 MHz, the pulse duration is 30 ps. After amplification, it stretches to 34.5 ps. The experiment enables the optical-to-optical conversion efficiency to reach 75%. To the best of our knowledge, this is the first report of such a high-power, narrow spectral linewidth, high peak power picosecond-pulse fiber amplifier based on a continuous-wave, mode-locked solidstate seeding laser. No amplified spontaneous emission and stimulated Raman scattering were observed when the pump was increased. © The Authors.
