PHPL-1500 Pulsed High Power Laser – 1465–1515 nm, >+18 dBm Output

High-Power Pulsed Laser for OTDR, Sensing, and Optical Instrumentation

The PHPL-1500 is a high-performance pulsed laser source designed for demanding optical applications such as OTDR, optical gas sensing, and precision instrumentation. With pulse output power exceeding +18 dBm and a tunable central wavelength from 1465 to 1515 nm, it offers exceptional power stability and wavelength accuracy.

Built with a semiconductor laser chip integrated with a fiber Bragg grating (FBG), this laser achieves outstanding performance in a 14-pin butterfly package with an SMF-28 fiber pigtail and FC/APC connector. It incorporates a thermoelectric cooler (TEC) and thermistor for reliable temperature control and consistent operation under varying environmental conditions.
