DBR Single Frequency Laser Diodes

Product information "DBR Single Frequency Laser Diodes"

632, 633 nm; Typ. Linewidth 1.0 MHz; Max. Output Power 10 mW CW; Threshold Current ≤120 mA; Slope Efficiency 0.4 W/A; Side Mode Suppression Ratio ≥30 dB

Toptica eagleyard’s 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.

Manufacturer "TOPTICA EAGLEYARD"

TOPTICA EAGLEYARD started as a spin-off from the Ferdinand-Braun Institut (FBH) in 2002. The core competence is the development, production and sale of innovative high-power laser diodes based on GaAs (Gallium Arsenide). Its portfolio contains laser diodes with wavelengths ranging from 630 nm to 1120 nm (DFB-lasers, tapered lasers, ridge waveguide lasers and broad area lasers). These laser diodes are addressing a variety of applications such as aerospace and defense, spectroscopy, medical instrumentation, test & measurement and material analysis.

DAFFI MT Interferometers for Multi-Fiber Connectors
Cost Effective; Field of View 3.3 x 2.7, 5.6 x 3.0 mm; Measurement Speed <5 s (+ calcul.); Output USB 3.0, 2.0; Connector Type MT 12/24, MT 16/32 (Male, Female, Ferrule), MPO 12/24, MPO 16/32 With DAFFI MT, Data-Pixel has developed a series of cost effective interferometers for multi-fiber connectors, suitable for high volume production without compromising accuracy or performance. Two versions are available, supporting MT-12 (DAFFI MT12) or MT-16 (DAFFI MT16) multi-fiber connectors. Based on Data-Pixel’s extensive interferometer manufacturing experience, the supplier designed the DAFFI MT interferometers to be robust, fast and accurate in order to meet all requirements of manufacturing or laboratory environments. With Data-Pixel’s BLINK software platform (included), DAFFI MT interferometers are able to measure the end face geometry on multi-fiber connectors and ferrules. The DAFFI MT interferometer accessories (flange and adapters) are fully compatible with the DAFFI SF, DAISI V3, DAISI MT FP and DAISI MT-V3 interferometers, allowing the user to limit the costs of the 3D geometry measurement units. DAFFI MT interferometers are compatible with Data-Pixel’s SUPERVISOR software, a MES style software which is in charge of the execution, management and monitoring of the production in an assembly workshop for fiber optic connectors. Its role is to supervise machines and help operators with complete traceability of the manufacturing information. Key Features: Measures PC APC Connectors and Ferrules True Phase-shifting Interferometer Non-contact Measurement Smart Autofocus, Focus Only When Required Automatic Calibration of Reference Mirror Supports MT-16 and MT-12 (DAFFI MT16 or DAFFI MT12) Vibration Insensitive Easy and Fast Switching From PC to APC, no Change of Fiber Holder Required Compliance with Industry Standards for Interferometer Measurements Intuitive BLINK Software With Data-base Connectivity Compatible with Desktop PC, Laptop, Tablet PC Applications: Measuring End-face Geometry of Multi-Fiber Connectors
