Excimer Optics
High Power Demands High Reliability
The excimer laser, a powerful source of UV radiation, has accelerated its move from the research laboratory to industrial and commercial applications such as photolithography, materials processing, semiconductor process and repair, laser marking, laser-assisted cleaning, eyesight correction and other medical applications. The excimer laser’s shift to commercial applications has created a demand for higher power levels and increased reliability from the laser itself, thus creating a greater...
