Tunable Diode Lasers Frequency-Converted Lasers

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.
