    • 1570-1580nm 8nm tunable bandwidth DBR laser diode     


    LD-PD's PL-DBR-1580-30-1-SA-14BF Distributed Bragg Reflector (DBR) laser is a single-frequency laser diode that is well-suited for low-noise pump applications, second harmonic generation and time-resolved fluorescence spectroscopy, and fiber optic sensor.

    The PLDBR1550PA includes an integrated optical isolator, thermo-electric cooler (TEC), thermistor, and monitor photodiode. It is packaged in a 14-pin butterfly package with SMF-28E single mode optical fiber and an FC/APC connector.
