633 nm; Typ. Linewidth 0.7 MHz; Output Power 10 to 100 mW CW (DBR); Threshold Current ≤70 mA; Slope Efficiency 0.7 W/A; Side Mode Suppression Ratio ≥30 dB

eagleyard Photonics’ DBR series of distributed Bragg grating (DBR) laser diodes contains a multi-section laser with gain, phase and distributed feedback (DFB) sections. DBR series laser diodes feature a built-in wavelength-selective grating stabilizing the wavelength

The DBR series’ resonator comprises a periodic structure. Thus, the devices operate on a single resonator mode emitting quasi-monochromatic radiation with a very small line width and low phase noise. The lasers can have very low-intensity noise because of the lack of mode partition noise. Due to the Gaussian mode the output is diffraction-limited..

Special variants are available, especially suitable for spectroscopy with mode‐hop free operation and small linewidth guaranteed at the specified target wavelength for spectroscopic applications – these laser diodes are reaching the target wavelength by temperature tuning and allow wavelength tuning around this target wavelength.

Key Features:
