Swift CW Frequency-Tunable Single-Frequency Laser
Description
The Swift is a compact, single-frequency, eye-safe diode-pumped laser optimized for use in coherent and direct detection lidar systems. Exhibiting high output power and < 10 kHz/ms short-term frequency jitter, the Swift is ideal for use as a master and local oscillator source in coherent lidar systems. Very fast and broad mode-hop-free frequency tuning enables next-generation spectroscopic applications like pollution monitoring and greenhouse gas measurements using differential absorption lidar techniques. This soon-to-be-released product will initially be offered using Tm,Ho:YLF operating across 2047-2059 nm wavelengths with multi-tens of GHz single-frequency tuning using an integral piezo actuator. The Swift capitalizes on Beyond Photonics’ decades of experience in the development and perfection of extremely stable single-frequency lasers. Other possible wavelengths include 1.06, 1.32, 1.5, 1.617, 1.645, 2.02, and 2.09 micron, with multi-nm set-ability across each central wavelength case. Please inquire about other wavelengths not listed.
