That illuminator integrates a laser diode and a driver board whose combination allows generation of nanosecond pulses. Laser diode design and manufacturing benefit from the sound know-how of Quantel’s Diode Department in hard solder technology already developed for QCW laser diodes to ensure efficiency and reliability. With its proprietary technology for nanosecond pulsed laser diode illuminators, Quantel offers unique laser sources that are compact, low-cost and highly efficient. While high output average power (typically higher than 2 W) will require a suitable cooling system, low output average powers make these laser diode sources ideal for integration into portable and even hand held devices. Typical applications are photoacoustics, NIR spectroscopy, ultrasound generation, 3D flash LIDAR or time of flight measurements.
