  • Amplitude Noise of 40-GHz pulses from a subharmonically synchronous mode-locked semiconductor laser
    IEEE Photonics Technology Letters, 2002
    Co-Authors: H.c. Bao, H.f. Liu, Yang Jing Wen
    Abstract:

    The broad-band Amplitude Noise of 40-GHz pulses from a subharmonically synchronous mode-locked (SSML) semiconductor laser is investigated. Experiments show that the Amplitude Noise of pulses generated from a SSML laser depends on the Amplitude Noise and pulsewidth of injected pulses, frequency detuning and subharmonic numbers.

  • Broad band Amplitude Noise of 40 Ghz subharmonically synchronous mode locked pulses
    , 2002
    Co-Authors: H.c. Bao, H.f. Liu, Yj Wen
    Abstract:

    Recently, subharmonic synchronous mode-locking and subharmonic hybrid mode locking, where the pukes are synchronized by injection of optical pubs and RF signal at a subhamonic of the cavity resonance frequency, have been developed to stabilise the passively mode locked pulses from semiconductor lasers [l-3], where the limitation imposed by drive electronics is alleviated. This paper provides a detailed experimental investigation of broad band Amplitude Noise in optical pulses generated by a SSML laser, continuing the work recently reported on Amplitude Noise of SHML pulses.

  • Amplitude Noise of subharmonically hybrid mode-locked pulses generated from a monolithic semiconductor laser
    IEEE Photonics Technology Letters, 2002
    Co-Authors: H.c. Bao, H.f. Liu
    Abstract:

    Broad-band Amplitude Noise (100 MHz to 20 GHz) of 40 GHz pulses generated by a subharmonically hybrid mode-locked (SHML) monolithic semiconductor laser is investigated. Experiments show that the Amplitude Noise can only be suppressed at some certain subharmonic numbers, while the phase Noise can be suppressed by subharmonic hybrid mode-locking under many subharmonic numbers.

  • Reply to the comments on Intensity Noise of an injection-locked Ti:sapphire laser: analysis of the phase-Noise-to-AmplitudeNoise conversion
    Journal of the Optical Society of America B, 2011
    Co-Authors: Jacopo Belfi, I. Galli, Giovanni Giusfredi, Francesco Marin
    Abstract:

    In reply to comments on our previous paper, we briefly discuss the usefulness of an injected Ti:sapphire laser systems for applications in spectroscopy and quantum optics experiments, and we clarify the role of the electronic servo loop in defining the Amplitude Noise of the system, already fully discussed in our previous publication [J. Opt. Soc. Am. B23, 1276 (2006)].

  • Intensity Noise of an injection-locked Ti:sapphire laser: analysis of the phase-Noise-to-AmplitudeNoise conversion
    Journal of the Optical Society of America B, 2006
    Co-Authors: Jacopo Belfi, I. Galli, Giovanni Giusfredi, Francesco Marin
    Abstract:

    We describe the characterize a compact ring Ti:sapphire laser injection locked to an extended-cavity semiconductor source. The laser system has a good spectral purity and allows for fast scans, keeping the injection-locking condition. We analyze experimentally the Amplitude Noise properties of the free-running and injected laser and show good agreement with a quantum-mechanical model. In spite of the sub-shot-Noise properties of the semiconductor source, the injected laser exhibits strong excess Amplitude fluctuations. We show that this effect is due to the conversion of the strong phase Noise of the semiconductor laser into Amplitude Noise of the injected Ti:sapphire laser.
