Buying Wavelength-swept Lasers
Wavelength-swept lasers are used in applications like optical coherence tomography (OCT), requiring periodic tuning of the laser wavelength over a specified range. These lasers can achieve large tuning ranges of 100 nm or more, with high sweep frequencies reaching tens or hundreds of kilohertz, and in some cases, even exceeding 1 MHz.

 7639 Cordner Lasalle, Quebec H8N 2X2 Canada |  O/E Land’s advanced swept laser source operates across the 1060, 1310, and 1550 nm ranges, utilizing an electrically tunable filter to provide bidirectional sweeping. For unidirectional sweeping, an electrical trigger is included, and an optical switch is available as an option. This versatile laser is ideal for fiber sensor systems, fiber component testing, optical coherence tomography (OCT), biomedical imaging, spectroscopy, and instrumentation. It offers an electrical square-wave trigger for synchronization, simplifying signal acquisition, especially when paired with an optional custom wavelength reference. The Fourier-Domain Mode-Locked (FDML) laser is a high-performance, ultra-fast swept source designed for applications that demand rapid and precise wavelength tuning. Covering the 1060, 1310, and 1550 nm spectral ranges, this laser delivers a broad tuning range with industry-leading sweeping rates of up to 4 MHz, ensuring both speed and high resolution. Optimized for OCT, spectroscopy, and metrology, the FDML laser provides high coherence length, low phase noise, and stable long-term operation. With medium to high output power, flexible control interfaces, and a compact fiber-based design, this laser offers reliable, seamless integration into a wide array of photonic systems.
