[aμs] offers beam shapers in form of the 2D- refractive microoptic arrays for beam homogenizing, e.g. transforming of the beam intensity distribution into the Gaussian one, enabling the uniformity up to 94%. The principal effect is based on the beam mixture by numerous, chaotically arranged refractive microoptic elements. Even uncoated, they provide over 90% efficiency. Available are beam shapers with divergence angles between 0.3° and 20° , they do not require careful adjustment and can be applied for lasers as well as for other light sources.
Gaussian laser beam shapers – LBH
Example of a designation: LBH– a –DVz(λ)
DVz –angle of divergency (grad)
λ -wavelenght (nm)
Applied materials are coded as follow:
Q – fused silica
GB – glass BK7
GT – glass S-TiH53 or S-TiH10
GL – glass S-LaH60
G – glass other type
P – plastic
P(G) – polymer lens on glass substrate
Microoptic spatial mode conversion for terawatt classamplifiers
The profiles of the amplified beam before (a) and after (b) the use of the micro optics to re-shape the pump mode are shown using an eight color gray scale and across a dynamic range of four orders of magnitude. The profile of the focus is shown with a gaussian whose near field profile has the same FWHM energy content.
