The JDSU Q Series lasers lead the market for high-power Q-switched diode-pumped UV lasers used for a wide variety of micromachining and solar cell processing applications. Whether for high pulse-energy processing of refractory materials such as silicon; high repetition rate processing of packaging materials such as Kapton; or patterning thin-film solar cells, the Q Series lasers deliver unsurpassed performance combined with industry-leading uptime. Due to the self-stabilizing characteristics of intracavity UV harmonic generation, all Q Series lasers exhibit inherently high pulse-to-pulse energy and long-term output power stability. In addition, the excellent thermal stability of the unique Nd:YAG-based direct-coupled pump (DCP) architecture maintains exceptionally stable beam position and profile, which is important for processes requiring accurate feature placement. These advantages enable Q series lasers to achieve the tightest possible process tolerances for micromachining and other materials processing applications.
