Flexible Laser-Ultrasonics From Lab to On-Site Demonstration

Tecnar's Lus system (especially the pulsed detection laser and the GaAs photorefractive crystal detection unit) was our “Enabler” to realize laser-ultrasonics projects with high impact for industry. Using those tools, we were not only able to realize measurements on industrial samples which are oxidized, rusty, dirty,… – but more importantly, we were also able to perform measurements in industrial production sites, directly in the aluminum and steel producing plants. Doing on-site measurements in industry has one important benefit: The industrial partner gains trust and belief in the measurement results! By this we were able to more than triple the number of our projects and to acquire a second Lus system.

Step 1

The Lus discovery combines:

Detection interferometer: Robust laser-ultrasonic detection unit based on a fast-response photorefractive crystal
CW detection laser: Frequency-stabilized continuous mid-power laser
Optical probe

Discover the simplicity
of laser-ultrasonics

The Lus discovery is the perfect starting point for your academic studies with laser-ultrasonics. The affordable, plug-and-play non-contact ultrasonic detection unit gives operators quick results on targets with reflective and low-scattering surfaces. The Lus discovery includes an optical probe linked via optical fibers. Users can choose any Tecnar probes or designs to meet specific research conditions. When the project advances to the next level, the Lus discovery can easily be upgraded to the Lus advance.

Step 2

The Lus advance combines:

Pulse detection laser: Proprietary long-pulsed high-power frequency stabilized laser
Detection interferometer: Robust laser-ultrasonic detection unit based on a fast-response photorefractive crystal
Optical probe

Move from the lab
to the real world

The Lus advance is a breakthrough technology that makes the industrial use of laser-ultrasonics routine. Tecnar’s proprietary detection laser is the key to the Lus advance’s easy and robust non-contact ultrasonic detection: the target’s surface condition, distance or angle is no longer a limiting factor for laser-ultrasonic applications. Researchers can then extend the use of laser-ultrasonics, while maintaining the flexibility of the Lus discovery set-up.
