DALGETY BAY, Scotland — Customized refractive diffusers from PowerPhotonic Ltd. enable beamshaping of high-power pulsed or CW lasers.
A freeform direct-write process is used to fabricate these highly nonuniform surfaces in fused silica.
The diffusers are designed to impart a defined intensity pattern in the far field. A variety of configurations are available, ranging from simple Gaussian diffusers to more complex beamshapers that create flat-top or annular spots.
All versions have tightly controlled angles of divergence ranging from fractions of a degree to 10° and potential transmission efficiencies >99 percent.
