    IR spectroscopy has never been easier. The powerful TOPOfrom Toptica 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 IR 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 BoosTA pro High-Power Tapered Laser Amplifier

    Toptica BoosTA pro High-Power Tapered Laser Amplifier

    The TopticaBoosTA pro, TOPTICA’s new stand-alone optical amplifier, increases the output power of a DL pro or any other linearly polarized master laser by up to 20 dB (x100). Following TOPTICA’s well-established pro-technology, the TA chip is mounted in a compact unit with optimized heat management and beam-shaping optics. A compact, external power supply (DC HP) drives the amplifier head and allows effortless operation - even of current-hungry TA chips at wavelengths with lower gain. Researchers thus benefit from output power levels up to 3.5 W.

    The BoosTA pro head includes a high-bandwidth current modulation board, which – when used in a closed feedback loop – allows compensating power fluctuations of the master laser by adjusting the amplifier gain. The board also features a protective circuit to avoid the risk of electronic chip damage. The beam management of the seed laser can be greatly simplified by optional fiber input coupling. Other options are optical isolators and fiber output coupling. The BoosTA pro head has sufficient space for a 60 dB isolator to protect the TA chip from back reflections.

  • Toptica DFB pro Distributed-feedback laser

    Toptica DFB pro Distributed-feedback laser

    Toptica Distributed feedback (DFB) lasers unite wide tunability and high output power. The frequency-selective element – a Bragg grating – is integrated into the active section of the semiconductor and ensures continuous single-frequency operation. Due to the absence of alignment-sensitive components, DFB lasers exhibit an exceptional stability and reliability. The lasers work under the most adverse environmental conditions – even in the Arctic or in airborne experiments.

    Three laser heads, designed specifically for DFB lasers, accommodate different diode packages: the compact DFB pro and its “big brother” DFB pro L integrate 9 mm or TO3-type diodes. The DFB pro BFY offers a dedicated laser head for butterfly-type diodes.

    Owing to their wide continuous tuning range, DFB lasers lend themselves particularly to applications in atomic and molecular physics, gas sensing, phase-shifting interferometry, and continuous-wave terahertz generation.

    New conveniences for working with frequency-converted diode lasers!

    TOPTICA’s latest DLC TA-SHG pro systems offer the lowest noise levels, narrowest linewidths and a simpler way to manage laser operation. Thanks to new, automated functions these systems revolutionize the daily work with frequency-converted lasers.

    Intelligent, automated alignment features integrated directly into the laser head transform the work with lasers: With the push of a button, the AutoAlign option re-optimizes the SHG system output power by maximizing the coupling efficiency of the laser into the TA chip and the SHG resonator via built-in intelligence and servo-controlled flexure mirror mounts. The PowerLock option automatically compensates residual drifts caused by changing environmental conditions, offering unvarying stable laser output with constant power. Fiber-coupled systems using the FiberMon option can monitor the optical power coupled to the SHG output fiber. In combination with the FiberMon option, AutoAlign and PowerLock are also available for fiber-coupled systems.
