Newport, a wholly owned subsidiary of MKS Instruments, a global leader in photonics and precision optical technologies, has published a series of technical whitepapers showcasing its latest advancements in laser diode characterization and test systems. These documents highlight the company’s commitment to enhancing laser performance through innovative tools and methodologies designed for precision, stability, and reliability.
The whitepapers provide detailed insights into core laser diode technologies, including tunable diode lasers and high-performance test and characterization systems. Newport’s instrumentation supports critical applications such as optical communications, sensing, and industrial laser development - areas where precise wavelength control, output stability, and accurate modulation are essential for device optimization and long-term performance.
The following whitepapers are part of the series released by Newport:
Tunable Diode Lasers
In this whitepaper, Newport introduces the operating principles and construction of tunable diode lasers, emphasizing their use in spectroscopy, telecommunications, and sensing. It describes external cavity diode laser (ECDL) configurations such as the Littman-Metcalf and Littrow designs, which allow single longitudinal mode operation and mode-hop-free tuning over broad wavelength ranges. These systems offer excellent side-mode suppression ratios (SMSRs), narrow linewidths, and high wavelength repeatability - key parameters for high-resolution applications.
