For more than a decade, Newport and its Spectra-physics lasers division have supplied laser and photonic solutions to the semiconductor industry. When the first mode locked quasi-cw ultraviolet lasers were introduced in early 2000, they opened up a whole new regime of material processing that used a very low energy picoseconds pulse at a very high repetationr rate.
