EP1550-ADF-B: 1550nm Telecom Laser Diode
The EP1550-ADF-B is a tunable single-frequency diode laser for gas sensing from Eblana Photonics. This laser which is available in a fiber-coupled 14-pin butterfly, TO-56, and TO-39 package, utilized Eblana’s proprietary discrete-mode (DM) technology to produces a tunable single-frequency laser with excellent side mode suppression ratio (SMSR), without the mode hops inherent to most distributed feedback (DFB) lasers. The EP1550-ADF-B has a center wavelength of 1550 nm, which can be tuned at a rate of 0.1 nm/oC while maintaining a maximum linewidth of 1MHz making it ideal for Acetylene (C2H2) gas detection. In addition to the excellent spectral properties of this laser diode, the EP1550-ADF-B also exhibits highly efficient power consumption, with a slop efferent of 0.12 mW/mA, requiring only 120mA of drive current at a maximum output power of 50mW.
All of these features make the EP1550-ADF-B laser a robust tool for gas sensing application, in an industrial, laboratory, or field setting.
