These optics are designed to impart a defined intensity pattern in the far-field, with a wide variety of distributions ranging from simple Gaussian diffusers to more complex beamshapers that create spots that are flat-top or annular; all with tightly co ntrolled angles of divergence ranging from fractions of a degree up to 10 degrees and potential transmission efficiencies in excess of 99%.

Matt Currie, Product Manager at PowerPhoto nic said, “designing diffusers for high power pulsed or CW lasers can be particularly challenging. Our design technique uses a new algorithm that allows for the design of surfaces that can precisely co ntrol the parameters of the laser source far-field by not o nly acting as a traditio nal diffuser but also shaping the intensity distribution of the beam at a system image plane. This gives us unprecedented flexibility to mitigate common problems such as hot spots and other non-uniformities while simultaneously maximising system performance.”

PowerPhoto nic presented a paper at Laser Munich 2015 on this new class of diffuser.
