Very interesting specs. What is this from ?
A dehumidifier integrated into the laser cooling system. Interesting.
Naval use I assume. And I believe it’s the right approach considering that naval vessels do have sufficient power and space for such a power hungry weapon.A dehumidifier integrated into the laser cooling system. Interesting.
It seems DRDO assumes the system will see prolonged deployments in very humid environments. May be the LORDS will become a component of coastal security in the future.
From tender I think it's the same 50kw laser system which drdo chief revealed about. And yes it will have ship motion compensation.Very interesting specs. What is this from ?
They are using water for cooling. Then the laser must be a Solid State laser. Water cooling is very risky & complicated business for Gas Dynamic lasers. Solid state lasers have an efficiency ~40%. That means 40% of the supplied power is converted to laser, the rest 60% is waste heat.
69kW is heat load of the laser. Assuming total power supplied to the laser source is "x". Then :
69= 60% of x
x= (69*100)/60 = 115kW
Therefore power of laser = 40% of x = (40*115)/100= 46 kW
A 46 kW Solid State Laser is pretty good for many military uses. The scalability of Solid State Lasers makes it very desirable for military applications.
From the looks, the current 50 kw is just the first phase of the DE-LWS project and is suitable only for protection against small UAVs and possibly the low flying cruise missiles. For bigger threats like jets and chopper is 100 kw is the threshold.
