MIR spectroscopy has never been easier. TOPTICA's 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 as the system tunes over its full range. A wide mode hop-free tuning range up to 300 GHz (10 cm-1) with a narrow linewidth (2 MHz, 1·10-4 cm-1) enables visibility of full spectroscopic signatures. Beyond the mode hop-free tuning range, the digital control enables simple stitching of multiple mode hop-free ranges for wide continuous spectroscopy.
Ease of use and reliable performance make this CW OPO the right choice for challenging applications: The TOPO can be applied to spectroscopy of molecular stretch vibrations for combustion analysis, trace gas detection, and ultracold molecular quantum technology. Its narrow linewidth and stability combined with TOPTICA’s locking electronics make it an ideal source for sensitive techniques like cavity ring-down spectroscopy and NICE-OHMS. In recent years, mid-infrared photonics devices have emerged as new platforms for gas detection, nonlinear frequency conversion, and mid-infrared frequency comb generation. The TOPO’s wide continuous tuning in the mid-infrared makes it easy to characterize such devices, and the same tools used for locking the TOPO to macroscopic cavities can be applied to integrated photonic cavities also. The TOPO can also be the backbone tool of a lab characterizing mid-infrared optical components and metamaterials.
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.
