Tunable mid-IR broadband single-frequency narrow-linewidth laser

MP-TNL-1-3400-1000-FSO is a mid‑infrared wavelength‑tunable laser based on optical parametric oscillation (OPO). It uses a highly stable fiber laser as the pump source to drive the OPO cavity. By adjusting the crystal parameters inside the OPO cavity, tunable output over the wavelength range of 3–4 μm can be achieved. Depending on the type of pump source, the MP-TNL-1-3400-1000-FSO can deliver watt‑level narrow‑linewidth continuous‑wave output. In continuous‑wave operation, the laser outputs megahertz‑level narrow‑linewidth radiation with wide‑range and high‑precision tuning characteristics, making it well suited for high‑resolution spectroscopy applications. The OPPO‑MIR tunable laser from Xiaoxiao Photonics features an integrated compact design, with fully automated software control for wavelength and power adjustment. It finds broad applications in remote sensing, detection, medical diagnostics, and infrared material characterization, and is particularly significant for the simulation of gas absorption lines in the ICL wavelength band.
