DBR Single Frequency Laser Diodes

760-1083 nm; Typ. Linewidth 0.6 MHz; Output Power 6-150 mW CW; Threshold Current ≤70 mA; Slope Efficiency 0.7 W/A; Side Mode Suppression Ratio ≥30 dBToptica eagleyard’s DFB series of distributed feedback (DFB) laser diodes features a built-in wavelength-selective grating stabilizing the wavelength. The DFB series’ entire resonator consists of 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.The choice of a distributed feedback design instead of a similar distributed Bragg grating (DBR) structure enables even a broader smooth tuning range around the operational point without the risk of experiencing spectral issues known as mode-hops, as these are given by design of a DBR diode, making the latter less suitable for the needs of atom spectroscopy.Special variants are available – two versions are intended to be used as seed lasers for pulsed fiber lasers, while other variants aim at oxygen detection as the emission wavelength of these laser diodes match with the strong absorption lines of oxygen at 760 nm and 764 nm while wavelength tuning around one of these absorption lines is possible.Further variants are 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.External backreflections may disturb the spectrum of these laser diodes, so the use of butterfly (BFW01) or TOC03 packages and effective optical isolation is recommended for spectroscopic applications requiring absolutely mode‐hop‐free tuning. Finally, special tunable variants with integrated optical isolators are available, enabling a wide mode‐hop free tuning range given by the specified operating temperature range and the specified power range.Key Features:Single Frequency ModeHigh Side Mode Suppression > 50 dBNarrow Linewidth <1 MHzPulse Width 1 to 50 nsPeak Power up to 500 mWRepetition Rate up to 1 MHzSMSR >35 dBProductWavelengthOutput PowerSpecificsDFB-0760-00012-1500-BFY12-0005760 nm12 mWoxygen detection, spectroscopy, metrologyDFB-0760-00040-1500-BFW01-0005760 nm40 mWoxygen detection with collimatorDFB-0760-00040-1500-TOV01-0005760 nm40 mWoxygen detection VCSEL replacementDFB-0760-00040-1500-TOC03-0005760 nm40 mWoxygen detectionDFB-0780-00020-1500-BFY12-0005780 nm20 mWoxygen detection,spectroscopy: Rb D2DFB-0780-00040-1500-BFY02-0000780 nm40 mWbasic variant with PM fiberDFB-0780-00040-1500-BFY02-0002780 nm40 mWtunable with PM fiberDFB-0780-00040-1500-BFW11-0005780 nm40 mWspectroscopy: Rb D2 with isolator and collimatorDFB-0780-00080-1500-TOV01-0005780 nm80 mWspectroscopy: Rb D2DFB-0780-00080-1500-BFW01-0002780 nm80 mWtunable with collimatorDFB-0780-00080-1500-BFW01-0005780 nm80 mWspectroscopy: Rb D2 with collimatorDFB-0780-00080-1500-TOC03-0000780 nm80 mWbasic variantDFB-0780-00080-1500-TOC03-0002780 nm80 mWtunableDFB-0780-00080-1500-TOC03-0005780 nm80 mWspectroscopy: Rb D2DFB-0785-00040-1500-BFY02-0000785 nm40 mWbasic variant with PM fiberDFB-0785-00040-1500-BFY02-0002785 nm40 mWtunable with PM fiberDFB-0785-00100-1500-TOV01-0000785 nm100 mWbasic variantDFB-0795-00015-1500-BFY12-0005795 nm15 mWspectroscopy: Rb D1 lineDFB-0795-00040-1500-BFW11-0005795 nm40 mWspectroscopy: Rb D1 with isolator and collimatorDFB-0795-00080-1500-BFW01-0005795 nm80 mWspectroscopy: Rb D1 with collimatorDFB-0852-00015-1500-BFY12-0005852 nm15 mWspectroscopy: Cs D2 DFB-0852-00050-1500-BFY02-0000852 nm50 mWbasic variant with PM fiberDFB-0852-00050-1500-BFY02-0002852 nm50 mWtunable with PM fiberDFB-0852-00100-1500-BFW01-0002852 nm100 mWtunable with collimatorDFB-0852-00100-1500-BFW01-0005852 nm100 mWspectroscopy: CS D2 with collimatorDFB-0852-00150-1500-TOC03-0000852 nm150 mWbasic variantDFB-0852-00150-1500-TOC03-0002852 nm150 mWtunableDFB-0852-00150-1500-TOC03-0005852 nm150 mWspectroscopy: Cs D2DFB-0895-00050-1500-TOV01-0005895 nm50 mWspectroscopy: Cs D1DFB-0935-00080-1500-TOC03-0004935 nm80 mWspectroscopy: YbDFB-1030-00500-1500-BFY02-00101030 nm500 mWseed laser (pulsed mode) with PM fiberDFB-1064-00025-1500-BFY12-00021064 nm25 mWtunable with isolator and PM fiberDFB-1064-00040-1500-BFY02-00001064 nm40 mWbasic variant with PM fiberDFB-1064-00040-1500-BFY02-00021064 nm40 mWtunable with PM fiberDFB-1064-00080-1500-TOC03-00001064 nm80 mWbasic variantDFB-1064-00080-1500-TOC03-00021064 nm80 mWtunableDFB-1064-00500-1500-BFY02-00101064 nm500 mWseed laser (pulsed mode) with PM fiberDFB-1083-00025-1500-BFY12-00021083 nm25 mWtunable with isolator and PM fiberDFB-1083-00080-1500-TOC03-00021083 nm80 mW Applications: Interferometry, Laser Doppler Velocimetry and Vibrometry; Cold Atoms; Optically Pumped Atom Clocks; Quantum Optics; THz Generation, Raman Spectroscopy; Cs- ,Rb- , K- Spectroscopy; Seed Laser for LIDAR SystemsPlease note that TOPTICA eagleyard products are not availble from us in Denmark, Finland, Iceland, Norway, and Sweden.
