Beam Homogenizer heightens UV laser efficiency.

Press Release Summary:

Fly's Eye Beam Homogenizer converts non-uniform beam of UV Excimer laser into homogeneous beam with 95% uniformity. Utilizing more than 80% of laser power, single element array adapts to most excimer lasers and offers working distances of 1-2 m with beam sizes of 8 mm to 1.5 cm. Product enables maximum amount of available laser power to be used, resulting in uniform, large area beam that can be subdivided using near-field imaging.

JPSA Fly's Eye Beam Homogenizer Boosts UV Laser Efficiency, Price/Performance Ratio

Hollis, New Hampshire, USA -- JPSA Laser's new Fly's Eye Beam Homogenizer converts the characteristically non-uniform beam of a UV Excimer laser into a homogeneous beam with 95% uniformity while utilizing >80% of the laser power. This long working distance single element array easily adapts to most commercial excimer lasers, and offers optimum price/performance ratio (single element for lowest cost and lowest beam loss). The JPSA Fly's Eye Beam Homogenizer's long working distance - typically between 1 - 2 meters - provides a beam size ranging from 8mm to 1.5 cm. It is easily re-imaged due to the long working distance and slow optical F-number.

Excimer laser beams are not perfectly uniform in intensity over the area of the beam and therefore only a portion of the area of the beam is usable for high-uniformity materials processing. In some cases, only the most uniform section or "filet" of the beam will be selected for use, and the non-uniform section of the laser beam will be discarded. Due to the premium price associated with UV photons, high beam utilization in many cases is a key economic factor. Beam shaping optics and beam homogenizers can be employed to shape the beam and simultaneously make the laser energy uniform so that the maximum amount of the available laser power can be used. The resultant uniform, large area beam can then be subdivided using near-field imaging to project complex patterns onto a part or make simultaneous multiple laser ablations, a key advantage of UV Excimer lasers.

JPSA products and services include UV excimer and DPSS laser micro machining systems, UV and VUV laser beam delivery systems, UV laser materials processing development, optical damage testing, and excimer laser refurbishment services. JPSA Laser operates a high-performance UV laser job shop as well as a systems engineering and manufacturing business.
