ECE Graduate Student Receives SPIE Scholarship


The International Society for Optical Engineering, or SPIE, has awarded a $2000 scholarship to David Alan Alessi, a Ph.D. student in electrical engineering at Colorado State University.

David's research at the National Science Foundation Engineering Research Center (ERC) for Extreme Ultraviolet (EUV) Science, under the direction of Professor Jorge Rocca, is centered on the development of compact and high repetition rate soft x-ray laser sources. During his undergraduate study, he, along with another undergraduate student, developed a magnetohydrodynamic code for simulating a capillary discharge plasma.

Alessi contributed to the development of laser pumped soft x-ray lasers in neon-like and nickel-like ions with wavelengths from 32nm to 11nm. These lasers have higher pulse energy and peak spectral brightness than alternative soft x-ray radiation from synchrotron and higher harmonic generation sources. "The development of compact high repetition rate soft x-ray laser technology has great potential to benefit fields such as EUV lithography, metrology, imaging, nanotechnology, high density plasma diagnostics, and spectroscopy," said David.

David has taken part in all aspects of the design, construction, and testing of a high power frequency doubled Nd:glass slab laser system. Upon completion, this laser will be used to significantly increase the pumping of a Ti:Sapphire laser system.

SPIE is the world's largest international not-for-profit society in the fields of optics, photonics, and imaging, with 17,500 individual members including 3,500 students. SPIE strongly believes in the opportunities and personal enrichment that education provides and in the need for increased scientific and technical literacy. The Society is committed to the upcoming generations of scientists and engineers who will develop the potential of optics and photonics.
