Physical Space and Equipment
The main lab space for the Laser Science Engineering Research Lab (LaSER), has three 30 ft by 30 ft rooms with six 12 ft by 4 ft Newport optical tables that are dedicated to optics and photonics research. The Center has over $ 10 million dollars of the latest in lasers and applied photonic measurement devices including a wide array of Ocean Optics spectrometers operating from 200 nm to 1100 nm, 2 Princeton Instruments intensified CCD cameras, Hamamatsu streak cameras, a series of StellarNet spectrometers ranging from 200-1700 nm, a Frequency Resolved Optical Grating (FROG) system for pulse diagnostics of femtosecond laser systems and two high speed, high definition LeCroy oscilloscopes ($40,000 each).
The LaSER Lab has a wide range of lasers spanning from femtosecond to microsecond pulse durations over a range of pulse energies and repetition rates. Additionally, LaSER Lab has multiple diode lasers ranging from 976 – 1500 nm along with the accompanying power supplies and controllers available for use. Each laser system has a set of nanometer-resolution 3D motorized translation linear stages in combination with rotation stage for complex and precise sample positioning. These stages are controlled using a custom-build LabView interface that is integrated with optical imaging systems for precise sample alignment.

Sample CharacterizationThe LaSER Lab has a Philips FEI evironmental scanning electron microscopy in the same room as the laser facilities for easy sample characterization. This SEM has a 25 nm resolution sample and is used extensively in laser damage measurements and aligning lens systems in femtosecond laser systems.
