Widely Tunable High-Power Continuous-Wave OPO Laser System for Mid-infrared Spectroscopy and Applications

  • 1.45 - 4.0 µm (2500 - 6900 cm-1)
  • 300 GHz (10 cm-1) mode-hop-free tuning range
  • Narrow linewidth: 2 MHz (1·10-5 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!
