Digital D-type with Isolator

DATASHEET

The OEM Single-Mode Digital D-Type Module offers high output power, narrow spectral bandwidth, and a diffraction-limited free space output beam. This module includes an internal thermistor and TEC, laser drive and TEC control electronics, an adjustable beam expander, and an optical isolator in a compact package. UART I/O connectivity and LabView customer GUI allow the user to control the device remotely.

The single-mode spectrum stabilized laser offers a narrow spectral bandwidth and super wavelength stability over time, temperature, and vibration. The laser's stabilized peak wavelength remains "locked" within a wide case temperature range. Devices can be tailored to suit specific needs, providing an extremely high signal-to-noise ratio, which is ideal for Raman spectroscopy.

*For custom orders, wavelengths can be accurately specified and repeatedly manufactured withn +/-0.1 nm upon request.*
