PDL Pulsed Detection Laser
- Generation of a high sensitivity laser-ultrasonic signal even on highly scattering surfaces
- Robust around the clock operation
- Easy maintenance
Tecnar’s PDL is a turnkey high power frequency stabilized laser source specifically designed for non-contact ultrasonic inspection. The PDL is based on a MOPA (Maser Oscillator Pulsed Amplifier) configuration which amplifies a low power seed laser to provide high peak power output. Using robust flashlamp technology for the amplification process, the PDL is built to sustain any environment, from laboratory to harsh industrial conditions.
In laser-ultrasonics the information is ‘encoded’ in the laser light reflected from the surface of the inspected part. To achieve optimum sensitivity with the laser-ultrasonic detection unit, maximisation of the illumination of the target is preferable. cw commercial lasers with the appropriate frequency stability are generally limited to under 2 W. In case of conditions with scattering surface, such power is insufficient to provide adequate signal to noise ratio. The PDL was specifically designed to overcome such problems.
The PDL is provided with large-core optical fiber delivery of up to 40 meters in length. Such flexible setup allows the PDL to be easily integrated in industrial prototype or commercial inspection systems.
