• 1.45 - 4.0 µm (2500 - 6900 cm-1)
    • 300 GHz (10 cm-1) mode-hop-free tuning range
    • Narrow linewidth: 2 MHz (1·10-4 cm-1)
    • Hands-free motorized tuning
    • Easy all-digital DLC pro control

    MIR spectroscopy has never been easier. The powerful TOPO delivers wide tunability, narrow linewidth, and convenient hands-free digital control. There are no modules to exchange and no adjustments to be made by hand. Ease of use and reliable performance make this CW OPO the right choice for challenging applications in MIR spectroscopy and quantum optics.

    The revolutionary TOPO by TOPTICA stands alone as the only fully automated, continuous-wave, singly-resonant optical parametric oscillator laser source on the market. High resolution spectroscopy across
    1.45 – 4.0 µm (2500 – 6900 cm-1) has never been easier.

    TOPTICA’s unique optical design enables broadly tunable laser light. No module or mirror exchange is necessary. Additionally, the all-digital control electronics enable hands-free coarse tuning, and frequency locking. A wide mode-hop-free tuning range up to 300 GHz (10 cm-1) enables visibility of full spectroscopic signatures. Simultaneously, the TOPO maintains a narrow linewidth (2 MHz, 1·10-5 cm-1) giving a solution that reveals narrow atomic and molecular features.

    TOPTICA's OPO laser system won the Prism Awards 2019 for scientific lasers at Photonics West!

    Options


    Narrow Linewidth

    The optical spectrum of the idler output is a convolution of the seed laser and signal spectra. The standard TOPO uses the DLC DFB pro as its seed, with 2 MHz linewidth. An alternate seed option is the DLC CTL 1050, which has < 10 kHz linewidth. This results in an idler linewidth of < 100 kHz.

    Fiber Coupling (FiberDock)

    TOPTICA’s patented fiber coupler provides highest single-mode fiber-coupling efficiencies, easy alignment and at the same time highest stability. With this option, fiber coupling is added TOPO signal and idler probe outputs for convenient power and wavelength monitoring. TOPTICA additionally offers a wide range of single-mode and polarization-maintaining fibers, including fiber-optic beam splitters.

    Laser Locking Electronics

    A broad variety of electronic locking modules is available for frequency stabilization.
