Illuminator for short pulses – ultra-compact OEM version

Pulsed laser diode illuminator

coche-blanche
Illuminator for vertical emission

From 30 ns - 1 mJ to 100 ns - 4 mJ

That illuminator can generate pulses from 30 to 100 ns with energies from 1 to 4 mJ depending on the pulse width. It can support pulse repetition rates in the range 1-6 kHz, depending on output energy per pulse, with a maximum average power of 6 W.

That module integrates a laser diode and a driver board mounted onto a copper plate, which makes this ultra-compact assembly ideal for integration into confined volumes. Various parameters regarding laser emission and electrical interface can be chosen by the customer. Components of that module have been selected to provide the highest possible efficiency, leading to a low power consumption, and the brightest possible emission. Additional equipment required to operate that illuminator, such as external power supplies, function generator and thermoelectric assembly for active cooling, can be provided as an option.

  • Energy and pulse width from 1 mJ/30ns to 4mJ/100ns
  • Maximal pulse repetition rate between 1 and 6 kHz
  • Up to 6 W average power
  • Single wavelength emission among 808, 915, 940 or 980 nm (other wavelengths in option)
  • Various beam geometry available
  • High reliability (> 100 x 109 shots)
  • Easy to integrate, robust design

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.
