• Matisse X-lightPound-Drever-Hall stabilized Matisse Lasers

    Sirah's Matisse lasers are now available with a stabilization that utilizes the Pound-Drever-Hall scheme. These lasers provide spectral linewidths to below 30 kHz. This extremely narrow linewidth is the result of very fast cavity length stabilization. To overcome the inevitable limits of piezo driven mechanics an electro-optical modulator (EOM) is added into the cavity, pushing the response bandwidth into the range of some MHz.
    The other key to achieve these ultra-narrow linewidths is the use of the Pound-Drever-Hall scheme. This method is renowned for being insensitive to all kind of spatial mode and intensity fluctuations and its fast response times. For applications where the advantage of the Pound-Drever-Hall lock needs to be combined with the high power of a laser without intra-cavity EOM Sirah offers the Matisse TX-light.

  • High Repetition RateHigh Repetition Rate Lasers

    Sirah's new Cobra HRR dye laser system is optimized for the use with high repetition rate and high pulse energy pump laser system. The Cobra HRR is designed for pump lasers with repetition rates in the range from 1 kHz to 10 kHz. The pulses are easily frequency doubled to attain wavelengths that are useful in applications like combustion diagnostics, or atmospheric research. The system already demonstrated to be a powerful tool in these applications.

  • EagleEye EagleEye Optical Spectrum Analyser

    The EagleEye optical spectrum analyser (OSA) is a compact unit for measuring the spectral characteristics of cw lasers.
    The EagleEye, like any other conventional OSA device, can analyse a laser spectrum by scanning the cavity. The resolution of thi method is limited by the cavity finesse, which is in the order of some megahertz.
    The EagleEye can surpass this limitation by using its unique lock, loose, and look procedure. This approach achieves a much higher spectral resolution. This technique enables the EagleEye to measure laser linewidth down to 20 kHz. [details..]
