Datasheet

Product Description

This upmarket multicolour diode illuminator integrates up to 4 diodes 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 quasi-continuous wave (QCW) laser diodes to ensure efficiency and reliability.

It can generate pulses from 80 to 130ns from up to 4 independent diodes. Each diode can emit a fast-axis collimated laser beam at one wavelength with an energy between 0.8 and 2mJ, depending on the pulse width. That leads to an overall emission of maximum 8mJ with one, two, three or four wavelengths in the same module. It can support a pulse repetition rate of up to 2kHz (higher frequencies, up to 10kHz, can be used in burst mode, i.e. a burst of 1 to 20 pulses emitted at a frequency lower than 100Hz). A maximum average optical power of 15W can be generated if used in combination with a suitable cooling system.

This unique high-tech module integrates up to 4 diodes and a driver board into a closed protecting housing and will then be particularly suitable for high average power generation at one wavelength or for multi-wavelength emission. Components of that module have been selected to provide the highest possible efficiency, leading to a low power consumption. An external beam shaping system is optional if beam superimposition and/or homogenization are needed. Additional equipment required to operate that illuminator, such as external low and high voltage power supplies, function generator and thermoelectric assembly for active cooling, can be provided as an option.

  • Up to 4 independent diodes assembled on top of each other in a compact volume
  • Fast axis collimation of diode bars included
  • High reliability (> 100 x 109 shots)
  • Robust design integrated into a closed protecting housing
