8.34um Benchtop High Power FP-QCL mid-infrared Quantum Cascade Laser 80mW (TDLAS integrated control module)
QCL8340FP-8.34um High Power Bench Top FP-QCL Mid-infrared quantum cascade laser is mid-infrared test laser developed by Idealphotonics in the first half of the year 2024. It has low atmospheric window loss, which is beneficial to space optical communication test research. Our bench top light source has high power and does not require ITAR review, making it an excellent choice for commercial mid-infrared test light sources. The tunable range exceeds 200nm, and the output power is greater than 80mW, which can meet the industrial needs of customer testing. Our laser has built-in Znse. The output is collimated and the output power is stable, and the temperature and wavelength stability are high , which is several orders of magnitude higher than the stability of traditional high-power quantum cascade lasers.
