Designed for OEM integration, IPS’s wavelength stabilized single frequency “A-Type” excitation source provides Raman system developers with a retro-reflection insensitive, wavelength stabilized laser alternative to existing thermally stabilized single-mode diode sources.  The A-Type module contains an integral diode laser, TEC, thermistor, laser line filter and beam shaping optics to provide a circularized and collimated Gaussian output beam. The A-Type module also features a unique high performance linear tracking photodiode that provides the user with linear output power measurements that can be used to create ultra stable APC control circuits or to normalize excitation power in quantitative Raman spectral analysis.  With output power levels in excess of 100 mW, spectral linewidth < 0.001 nm and power stability < 0.5%, the A-type module is ideal for high performance and confocal Raman spectroscopy.
The A-Type module measures 3” x 1.18” x 1” and weighs in at < 2.5 oz.  The unit may be mounted from either the front face or bottom base plate, and has a threaded beam outlet to accommodate a beam expanding collimator.  The A-Type may be purchased as a stand alone optical head or as a turn-key OEM system with integral laser drive and TEC control electronics attached to the head via supplied cable assemblies.
IPS’s A-Type module is available at 785 nm, 808 nm, 830 nm, 976 nm, 1064 nm and at 1546 nm.  Custom wavelengths are available upon request.
