  • Quantum Electronics Letters Efficient Difference Frequency Oscillator Based On a Ti : Sapphire Laser
    1991
    Co-Authors: S.g. Bartoshevich, I.v. Mikhnyuk, G.a. Skripko, I.g. Tarazevich
    Abstract:

    A high efficiency coherent radiation source, based on a Ti : sapphire laser and nonlinear crystals, operating in the spectral range from 0.34 to 2.3 pm, has been considered. For this purpose a Ti : sapphire dual-wavelength laser has been de- veloped where the process of self-synchronization of both chan- nels has been realized. A difference Frequency Oscillator with 2 w, - wI and 2 wI - w,, including the spectral range from 0.503 to 0.79 and from 0.83 to 2.3 pm has been realized. The great attention has been given to the temporal characteristics of the DWL.

  • Efficient difference Frequency Oscillator based on a Ti:sapphire laser
    IEEE Journal of Quantum Electronics, 1991
    Co-Authors: S.g. Bartoshevich, I.v. Mikhnyuk, G.a. Skripko, I.g. Tarazevich
    Abstract:

    The problem of expanding the Ti:sapphire laser wavelength range by generating difference (sum) frequencies is discussed. The authors present a high-efficiency coherent radiation source, based on a Ti:sapphire laser and a nonlinear LiIO/sub 3/ crystal, operating in the spectral range from 0.34 to 2.3 mu m. For this purpose a Ti:sapphire dual-wavelength laser has been developed where the process of self-synchronization of both channels has been realized. A difference Frequency Oscillator with 2w/sub s/-2w/sub l/ and 2w/sub l/-w/sub s/, including the spectral range from 0.503 to 0.79 and from 0.83 to 2.3 mu m, has been realized. A detailed study of the temporal characteristics of Ti:sapphire lasing is given, the development of methods for mixed pulse overlapping is discussed, and other subjects, such as configuration of widely tunable coherent radiation sources, are addressed.

  • electro opto mechanical radio Frequency Oscillator driven by guided acoustic waves in standard single mode fiber
    arXiv: Applied Physics, 2018
    Co-Authors: Yosef London, Hilel Hagai Diamandi, Avi Zadok
    Abstract:

    An opto-electronic radio-Frequency Oscillator that is based on forward scattering by the guided acoustic modes of a standard single-mode optical fiber is proposed and demonstrated. An optical pump wave is used to stimulate narrowband, resonant guided acoustic modes, which introduce phase modulation to a co-propagating optical probe wave. The phase modulation is converted to an intensity signal at the output of a Sagnac interferometer loop. The intensity waveform is detected, amplified and driven back to modulate the optical pump. Oscillations are achieved at a Frequency of 319 MHz, which matches the resonance of the acoustic mode that provides the largest phase modulation of the probe wave. Oscillations at the frequencies of competing acoustic modes are suppressed by at least 40 dB. The linewidth of the acoustic resonance is sufficiently narrow to provide oscillations at a single longitudinal mode of the hybrid cavity. Competing longitudinal modes are suppressed by at least 38 dB as well. Unlike other opto-electronic Oscillators, no radio-Frequency filtering is required within the hybrid cavity. The Frequency of oscillations is entirely determined by the fiber opto-mechanics.

    2018 Conference on Lasers and Electro-Optics (CLEO), 2018

    Abstract:

    An electro-opto-mechanical feedback loop is established across two cores of a multi-core fiber. Guided acoustic waves are stimulated into single-mode oscillations at 369 MHz with 400 Hz linewidth. Threshold behavior and spectral narrowing are observed.
