At less than 10 % of cost, the patent-pending Photon Trap can facilitate realistic simulation of CW High Energy Lasers (HEL) at a portable/deployable platform for:
laser power calibration
optics damage threshold measurement
beam propagation characterization for Test and Evaluation (T&E) of High Energy Lasers
Photon Trap Model: PT-500kW
Prototype Photon Trap PT-500kW specification
Maximum intracavity laser power: 500 kW
Pumping diode power: <1 kW
The Radiation Pressure Meter measurement of the PT-500kW system as a function of the intracavity laser power that was measured optically by monitoring the leakage laser power through the end mirror.
Demonstration of Dielectric Mirror Damage Threshold Measurement with PT-500kW
A damaged high power dielectric mirror during the CW laser damage threshold measurement:
- Mirror reflectance >0.999.
- Mirror diameter: 2.5 cm
- Intracavity laser beam power at the damage threshold: 260 kW
- Intracavity laser beam diameter: 0.6 cm
- Measured CW damage threshold: 920 ± 80 kW/cm2.
