200-kHz Swept Light Source for OCT Imaging

05/07/2012 NTT-AT introduces new swept light source for OCT imaging. - High-speed: 200-kHz A-line rate - Voltage-controlled sweeping formats: k-linear scan available - Coherence length > 7 mm at 200 kHz Scan* - All solid state: no moving parts  

Scalable High-Power and High-Brightness Fiber Coupled Diode Laser Devices - Photonics West 2012

04/26/2012 In this paper we present a detailed characterization of different diode laser sources based on the scalable modular concept. The optical output power is scaled from 180 W coupled into a 100 μm NA 0.22 fiber up to 1.7 kW coupled into a 400 μm NA 0....

Design and Test of Fast Laser Driver Circuits

03/30/2012 In industrial laser systems and measurement applications, the designers are challenged with the very demanding task to design and verify fast driver circuits. This White Paper describes the design of fast driver circuits, PCB layouts and optical m...

High-power diode laser pumps for alkali lasers (DPALs)

02/22/2012 We present performance data of recent high-power laser diodes emitting at typical pump wavelengths for alkali vapor lasers: 852 nm for cesium, 780 nm for rubidium, 766 nm for potassium, and 670 nm for lithium atoms. Due to different approaches in ...
