Fall 2006 Page 9HeliosTransient Absorption Spectroscopy SystemAbsorption spectrometer for ultrafast phenomena.Helios is a CCD-based pump-probetransient absorption spectrometerused for monitoring extremely shortlivedoptically absorbing states. Theexperimental time window rangesfrom 150fs to 3.2 ns, coveringwavelengths of 350 to 1600 nm. Thesystem comes with anoptical unit and a PC thatcontains data acquisitionhardware and software.The system is designed towork with an amplifiedTi:Sapphire femtosecond laserto produce spectral and kineticdata required forinvestigating photoexcitationevents onthe sub-picosecond andlonger timescale. The systemproduces a 3-D Wavelength-Time-Absorbance data matrix in an ASCIICSV file, which can be easilyprocessed and displayed using theSurface Xplorer software.Key FeaturesQuick, easy installationEasy accommodation ofharmonic generators and OPAsSuperb data analysis softwaretoolSee our website for more info.WEB newport.comOpal ®BBHigh-Power Synchronously Pumped OPOOffers higher power than any other commercial OPO.Key FeaturesHigh output powerSimple automated wavelengthscansThe Opal BB is an optical parametricoscillator (OPO) that delivers broadlytunable femtosecond pulses from 1.1to 2.25 µm with a single set ofoptics. It further extends output ofthe Mai Tai HP and Tsunami ultrafastTi:Sapphire lasers into the infrared.In addition, Opal BB also providesfrequency-doubled wavelengths inthe “missing” visible region.This robust OPO accepts higherpump power than other bulk orperiodically poled materials. As aresult, the Opal typically produces> 600 mW at 1.3 µm and > 400 mWat 1.5 µm. For ease of use,operational and wavelength tuningfeatures are automatically controlledby a built-in computer, which can beinterfaced using an RS-232 or GPIB.Wide continuous spectralcoverage by a single set of opticswith synchronized signal andidler outputsMode-locked output pulsesSee our website for more info.WEB newport.comwww.newport.com
