• New PrecisionScan NEW PrecisionScan

    Sirah has re-invented the pulsed dye laser. The new PrecisionScan is redesigned from scratch. The system is now more compact, occupying less table space. The controls for the laser are now oriented to the top side. The lid of the laser can be attached to front and backside of the laser. So, operation from any side and free placement of the pump laser is possible. Also, the laser comes now with a touchpanel remote control. As always with Sirah lasers easy computer control via an USB port is possible.
    A completely new feature is the automatic grating exchange (patent pending). Two gratings are mounted on a high precision linear stage allowing a rapid change of the grating without the need for a full re-calibration of the system. This allows to operate always with a perfectly matched grating, without gaps.

    • Matisse with New Reference Cell (click to enlarge) Fibre Coupled Reference Cell for Matisse Lasers

    Sirah's Matisse lasers are now available with a fibre coupled reference cell . The cell has a smaller footprint than the previous free-air design. It requires less table space and the cell can be placed more freely with respect to the laser. Also, the finesse of the cavity optics are now better matched to the laser and control loop characteristics.
    Furthermore, the bandwidth of the "tweeter" piezo is increased. The bandwidth determines how fast the control electronic can compensate deviations of the laser frequency. So, higher bandwidth means less laser linewidth.
    On top of that, Sirah introduces a new release of the control box firmware that supports faster control action and active compensation of the etalon dither. The effort pays off in an improved linewidth of the Matisse system, which is now specified to be 75 kHz for the actively stabilized Titanium:Sapphire model.

  • CredoIntroducing: The Credo

    The Credo is Sirah's radical new design for high repetition rate pulsed dye lasers. The compact system is perfectly matched to DPSS pump lasers with high repetition rate and low or moderate pulse energy. All the Credo's components, such as resonator, dye cells, amplifier, circulation system have been thoroughly designed with the goal to built an easy to use, efficient laser system. The result is laser system that achieves an unpreceded output well above 10 Watt . With the built in frequency doubler a stunning power of 1.5 Watt in the uv are achieved.
