Itasca Solid-State Laser Module


The Itasca solid-state laser module is a uniquely-designed laser source for TSI’s Laser Doppler Velocimetry (LDV) and Phase Doppler Particle Analyzer (PDPA) systems.

Product Details

This Itasca solid-state laser module provides integrated frequency shifted and unshifted beams, making it ready to generate the measurement volume in LDV or PDPA arrangements with the TSI’s fiber optic probes. The powerful and stable laser module operates without the need for external cooling, and operates on standard wall plug power supplies.

It is ideal for your research using LDV or PDPA system because it provides to two laser beams as the output, one shifted at 40 MHz and the other unshifted, ready to be coupled to the fiber optic probe (transceiver and transmitter) to generate the measurement volume for the system.

The high laser power of 1W for each wavelength is very beneficial for your challenging measurements in boundary laser flow or with long standoff distance which typical signal-to-noise is low. The high laser can boost the signal to get accurate measurement even in this type of circumstance.

The Itasca laser module makes the entire LDV and PDPA optics a breeze for system setup, allowing you to spend time for your research, not adjusting the optics continuously.
