DSTG seeking industry partners for defence technology

The Defence Science Technology Group is looking for industry partners interested in licensing and commercialising its Directed Infra-Red Counter-Measure (DIRCM) concepts.

The Laser Technology Group at DSTG has continued its research in the development of lasers for DIRCM applications. The DSTG-proposed new generation fibre laser technology replaces a large fraction of the solid-state laser with a monolithic fibre laser amplifier. Fibre lasers are far less sensitive to vibration and, as a result, are cheaper and easier to manufacture.

"[DSTG’s] new generation fibre laser technology will significantly improve the stability of the laser in harsh conditions and reduce the manufacturing costs," said Defence laser scientist Nikita Simakov.

"The technology also offers performance advantages: operating at higher average powers than bulk crystalline lasers, and with higher peak powers and better beam quality than diode lasers.

"In addition, fibre-based systems are less sensitive to vibration and mechanical deformations, offering superior performance and cost savings when integrated on defence platforms."

The DIRCM concepts are designed to protect aircraft from increasingly sophisticated guided missiles.

DSTG said heat seeking missiles and electro-optic sensors remain a threat to defence platforms, especially to ‘stealth’ platforms that are only stealthy in certain portions of the radio frequency spectrum.

Currently deployed DIRCM systems use bulk crystalline solid-state lasers to produce the laser radiation required to defeat thermal heat seeker sensors on missile threats. Such lasers are sensitive to vibration and as a result are difficult to engineer and expensive to ruggedise for integration onto a defence platform.

Despite these challenges, DSTG has successfully developed and transitioned several generations of this laser technology to industry.
