AERI/HEL technology: next-generation interceptor laser systems for anti-fighter, anti-missile and anti-ICBM applications ( AERI/HEL surface-to-air defence system ) & laser fusion Part 8
1. Breakthrough technologies have been realised in AERI/HEL technology to overcome some of the problems with lasers. In other words, it is an epoch-making and innovative technology that opens up the possibility of overcoming the three problems of (1) insufficient output, (2) energy attenuation due to atmospheric diffusion and (3) the resulting limitations in range.
2. ultrashort-wave laser pulses that can be generated by AERI/HEL technology (AERI/ultrashort-wave laser pulses) are pulsed lasers with ultra-short pulse widths of femtoseconds (10-15th power 1/1000 trillionth of a second). The energy is extremely high: several 1.0 terawatts (TW: a terawatt is 10 billion kW).
In continuous oscillation mode (CW mode), the energy is about 50 MW.
3. The atoms in the colliding atmosphere are instantly ionised, forming fibres of plasma along the AERI/ultrashort-wave laser pulses. By balancing the complex interrelationship between the electromagnetic field of the pulse and the plasma fibres, the AERI/ultrashort-wave laser pulse is no longer dispersed in the atmosphere, but conversely converges on itself.
4. as a result, the shooting distance of high-power lasers in the low-power class of conventional lasers is limited to around 10 km, whereas the shooting distance of A ERI/ultrashort-wave laser pulses can reach much further than this, reaching ultra-long-range shots of over 200 km.
5. more conveniently, AERI/ultrashort-wave laser pulses contain lasers of all visible wavelengths, making this type of laser light white as a whole. The white colour combines with an innovative information transmission capability that allows laser beams of various wavelengths to be sent, thus dramatically increasing the amount of information that can be transmitted.
