materials processing facility enables fundamental and applied research in a variety of different fields, including integrated optics, advanced materials science, photochemistry, life sciences, and manufacturing. The ultrafast transfer of energy from laser pulses to the material ensures higher spatial (sub-micrometer) and temporal (sub-picosecond) selectivity of the materials processing, as well as a significantly reduced heat input compared to longer laser pulses. The low repetition rate reduces cumulative heating between pulses, making this facility ideal for the research on heat-sensitive applications such as ablative processing and light-matter interaction with biological specimens. The high intensities that can be generated with femtosecond laser pulses enable the exploration of the non-linear absorption mechanisms utilized for the processing of dielectric materials. The ability to utilize single femtosecond pulses allows an implementation of pump-probe experiments for time-resolved studies of various laser-matter interaction phenomena.<br \/><br \/>In addition to the fundamental wavelength at 800 nm and its second harmonics at 400 nm, the facility is equipped with a femtosecond optical parametric amplifier (fs-OPA) that extends the output wavelength range into the near- and mid-IR. The ability to tune the frequency of the ultrafast laser light can be utilized for laser processing of wide band gap materials and spectroscopic studies.<br \/><br \/>The primary utilization of the facility within the Laser &amp; Plasma Laboratory at the Townes Laser Institute covers the fabrication of 3D volumetric optical and microfluidic structures in transparent materials, high-precision machining of different classes of materials, and time-resolved studies of laser-matter interaction in different materials.<\/p><h4>Facility Equipment<\/h4><p><strong>Femtosecond Chirped Pulse Amplification (CPA) laser light source<\/strong><\/p><p>Spectra Physics Spitfire<\/p><ul><li>Max pulse Energy &gt;1 mJ<\/li><li>Pulse duration ~110 fs<\/li><li>Wavelength 800 nm, 400 nm<\/li><li>Repetition rate 0 \u2013 1 kHz, single pulses<\/li><\/ul><br \/><p><strong>Femtosecond Optical Parametric Amplifier (fs-OPA)<\/strong><\/p><p>Coherent OPerA<\/p><ul><li>Wavelength range 1.1 \u2013 2.6 micrometer<\/li><li>Max pulse energy &gt;0.2 mJ<\/li><\/ul><br \/><p><strong>3D computer-controlled positioning system<\/strong><\/p><p>Newport VP-25XA<\/p><ul><li>Spatial resolution 100 nm<\/li><li>Max travel 25 mm<\/li><li>Max speed 25 mm\/s<\/li><li>LabView programming environment for custom motion and shutter control<\/li><li>Imaging system for reflection and transmission illumination modes<\/li><li>Vertical beam delivery for dry and liquid materials processing<\/li><\/ul><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"Khz Femtosecond Laser Materials Processing Facility The kHz femtosecond laser materials processing facility enables fundamental and applied research in a variety of different fields, including integrated optics, advanced materials science, photochemistry, life sciences, and manufacturing.
