Spectra-Physics has introduced its Explorer One, an actively Q-switched diode-pumped solid-state ultraviolet laser. The design combines laser resonator and control electronics into a single housing.
Explorer One lasers are targeted for a variety of applications such as MALDI-TOF mass spectrometry, laser microdissection, UV plastics marking, stereolithography, FPD repair, and other tasks. This first generation of Explorer One lasers will be available in two versions at 349 and 355nm wavelengths.
Explorer One 349-120 delivers a high pulse energy of >120µJ at 1kHz repetition rate. Explorer One 355-300 delivers >300mW output power at 50kHz repetition rate. Both lasers have short pulse widths (<5 and <8ns, respectively) and low pulse energy noise (< 2 per cent and < 3 per cent, respectively).
