The experimental team in the Physics Department at Rutgers-Camden shares a common experimental laboratory, located in the new Camden Nursing & Science Building (CNS) that was opened in the Fall of 2017. Approximately 2000 square feet of space was custom built to suit the unique needs of the Laser Material Interactions Laboratory. Given the urban setting that this building is in, several steps were taken to remediate vibrations. The lab is located on the ground floor and was built on an isolated foundation. All vibration sensitive equipment is placed on a custom designed 144 square foot Newport optical table. The space is divided into five separate rooms: a wet chemistry lab, characterization lab, laser lab, student workspace, and an isolated entryway for addition laser safety. The laboratory is secured with card access, and building access is controlled by on-site security.

The department recently acquired a unique ultrafast laser system integrated with a research-grade optical microscope funded through NSF-MRI award #1531783. The laser is a femtosecond Ti:sapphire system pumping an automated optical parameter amplifier with sum-frequency and harmonic generation stages that allow for a broad selection of wavelengths (240-2400 nm). The selected output is steered into a fixed-stage upright microscope; whereby, the optical and laser paths are made collinear via dichroic mirrors. Additionally, a 785 nm CW diode laser has also been combined into the optical path to facilitate optical tweezing.

The instrumentation is meant to dramatically expand the scope and significance of research being conducted in southern New Jersey in the areas of: ultrafast laser ablation/machining, membrane photoporation/phototransfection, plasmonic nanoparticle scattering, and multiphoton absorption polymerization.

Key components:

• Spectra Physics Solstice ACE 100F1K Ti:Sapphire laser (800 nm fundamental, 120 fs, 6 mJ, 1000 Hz) + 3rd Harmonic generation and TPR-TOPAS for generation of light from 240 nm-2400 nm

•Zeiss AxioExaminer Z1 fixed stage upright microscope - can perform fluorescent, darkfield, and phase contrast imaging.

•Andor Kymera193i Spectrograph equipped with dual exit ports to which we have attached an iStar iCCD and a Neo5.5 sCMOS cameras.

Beamtime with the system is available to both internal and external users with special priority given to investigators from institutions located in South Jersey. Interested parties should contact Dr. Sean M. O'Malley ( to discuss wheather the capabilities of the system can meet the needs of your research project.
