Diode lasers developed for applications requiring high wavelength stability and narrow linewidth. They are commonly used in Raman spectroscopy measurements.
Lambda Beam Wavelock is a diode laser developed for applications requiring high wavelength stability and narrow linewidth. It is particularly used in Raman spectroscopy measurements due to its high wavelength stability. The output method can be selected from spatially collimated output or fiber output (SM or PM fiber). The controller can be chosen from two types: a Power Controller that allows key switch operation and a Powerbox that is also ideal for embedded applications. <Features> - Maximum output: 500 mW - Multi-wavelength: 405~808 nm - Linewidth: Minimum 0.05 pm - Output stability: <1 %@10h - Wavelength stability: <0.015 nm - Coherence length: Up to 10 m - Includes software for Windows
