To achieve the narrowest possible linewidth, we recommend using a driver with low drive current noise, such as our LDC series of drivers. These DBR lasers are compatible with Thorlabs' line of laser diode drivers and temperature controllers. These lasers offer narrower linewidths compared to our DBR lasers. For additional single frequency laser options, Thorlabs also offers external cavity, butterfly-packaged single frequency lasers. Clicking on the red Docs icon ( ) next to the serial number provides access to a PDF with serial-number-specific L-I-V and spectral characteristics. After clicking "Choose Item" below, a list will appear that contains the center wavelength, output power, and operating current of each in-stock unit. The center wavelength of a particular unit varies from production run to production run, so the diode you receive may not operate at the typical center wavelength. While the center wavelengths are listed for the laser diodes below, they are only the typical values. For additional protection from back reflections, each of the butterfly package DBR lasers includes an internal optical isolator. DBR lasers are extremely sensitive to back reflections, which necessitates the use of the angled FC/APC connector. The butterfly package includes an integrated thermoelectric cooler (TEC), thermistor, monitor photodiode, and a single mode or polarization-maintaining output fiber with an FC/APC connector. These DBR lasers are housed in a compact 14-pin, type-1 butterfly package, enabling compatibility with any standard 14-pin laser diode mount (such as item # LM14S2). For a complete list of specifications for each DBR laser, click on the blue Info icons ( ) in the tables below. Please refer to the specifications for tuning coefficients. The output wavelengths of these lasers are current- and temperature-tunable. These lasers produce higher output powers than DFB lasers and achieve typical linewidths less than or equal to 10 MHz with an excellent side mode suppression ratio (50 dB typical). Thorlabs' Distributed Bragg Reflector (DBR) lasers are narrow-linewidth, single-frequency (single-longitudinal-mode) laser diodes that have a monolithically integrated Bragg mirror outside of the active region.
