Laser Tech Training Program
With the current situation regarding On-Campus Educational instruction, the Laser Tech Training Program is planned to be moved to Pasadena City College this summer with courses beginning this Fall. This, however is subject to change depending of circumstances.
Check back here over the coming months to see updates. The following notes will remain true.
Laser and Photonics Technology instructors lead hands-on, laboratory-driven classes, utilizing state-of-the-art industrial equipment, based on the industry-guided photonics curricula written by industry professionals. In addition to laboratory skills, students are offered one-on-one support and career advice, including résumé and LinkedIn profile building.

LightSail 2 - Achieving Flight By Light
Justin Mansell, Planetary Society &
Purdue PhD Candidate
Abstract: In July 2019 the LightSail 2 CubeSat unfurled its 32 m2 solar sail in space above the Earth. Then, tacking the sail like the sea-fairing vessels of olde, the spacecraft succeeded in changing its orbit using the pressure of sunlight. The achievement was the culmination of a 10-year crowd funded program sponsored by The Planetary Society to raise the public and technical profiles of solar sailing through a pair of flight experiments. Unencumbered by limited propellant, the technology has the potential to enable entirely new types of space missions, including feasible travel to other stars. But while the concept of solar sailing is centuries old, its realization is new and there is much to learn. This talk will describe the major challenges faced during the LightSail 2 mission, along with the achievements and lessons that resulted. The flight team continues to refine solar sailing and conduct imaging from the spacecraft to engage the public interest and deepen the mission’s technical impact.
Upcoming SCAVS Event
Friday 19 June
The Southern California Chapter of
the AVS invites you to a tour of
the James Webb Space Telescope (JWST)
During the tour, participants will be brought into the M8 James Webb Viewing Area to view the observatory itself. The guided tour will include the following highlights:
▪ The guide will explain the science objectives of James Webb and touch on the history of the observatory.
▪ Participants will learn about how the science informed the design of the James Webb
▪ Details on how the James Webb team overcame the engineering challenges necessary to build the observatory will also be discussed.
▪ The guide will point out interesting features visible from the viewing window.
▪ Participants will be given an opportunity to ask questions.
The M8 James Webb Viewing Area is split into two (2) areas: a Top Deck and a Bottom Deck. The Top Deck is accessible only by climbing a flight of stairs, but the Bottom Deck is fully accessible. On typical tours, both decks are visited.
The tour will be held at Northrop Grumman Space Park in Redondo Beach, CA, in the M8 James Webb Viewing Area. Participants should assemble outside the north end of building M8 at least 10 minutes prior to the start of the tour. Parking is available along Mettler Drive and north of M8. The tour will last approximately 45 minutes. There is no charge for this tour.
▪ Only US citizens may participate in this tour.
▪ Please advise tour coordinators if you have special accommodation needs.
▪ No food or drink is allowed in the Viewing Area.
▪ All visitors will be required to sign the Visitor Logbook in the Viewing Area.
▪ This tour will visit only the M8 Viewing Area and participating on the tour does not permit you access to any other facility at Space Park.
▪ You must be escorted at all times by the tour guide while in the M8 Viewing Area.
▪ No photography is allowed on site and there will not be provisions for having your picture taken with the James Webb.

Multiphoton Imaging of Human Skin
Abstract: Multiphoton imaging of human skin provides access to morphological information with molecular contrast obtained in a noninvasive manner. Our group at Beckman Laser Institute pioneered the clinical skin imaging with multiphoton microscopy. This talk will present the latest developments on the new generation multiphoton microscopy imaging platform for efficient integration into clinical setting.

Intelligent Positioning in High Throughput Photonics Manufacturing Automation
Abstract: In Silicon Photonics and other precision optical fields, production quantities have exponentiated and competition has intensified over the past few years. In multiple test and packaging steps, submicron-scale alignments are necessary and dominate overall production costs. These commence with optically and electronically probing devices while still on the wafer, and the alignments must be repeated through final packaging and all the intermediate steps in between.
The key is leveraging optical physics to separate dependence on position commandability. A universal implementation is now commercially available and fab-proven. Process cost reductions of 99% are seen. We will discuss this technology and its applications, and a live demonstration of parallel array I/O alignment will be offered.

The Supernova Acceleration Probe (SNAP)
Studying Dark Energy in the Universe
Abstract: The Supernova Acceleration Probe (SNAP) was a proposed experiment designed to quantify dark energy by measuring the redshift-magnitude diagram of supernovae and to quantify the growth of structure in the universe by measuring weak gravitational lensing over cosmological distances. These techniques, along with baryon acoustic oscillation, are used to constrain dark energy density and matter density in modern cosmological models. The baseline SNAP telescope was an ambient temperature, annular-field, configuration II Korsch, three-mirror anastigmat (TMA), designed to fly at the L2 Earth-Sun Lagrange point. The SNAP project evolved into the Joint Dark Energy Mission (JDEM), and finally the Wide-Field Infrared Survey Telescope (WFIRST). Stray light analyses of the SNAP telescope included both overall systems engineering and budgeting, and detailed non-sequential modeling of the effects of dust, roughness and thermal infrared emission, as well as stop placement and baffle design. The goal of the stray light design was to ensure that stray light in the 0.4 to 1.7 micron wavelength range did not exceed a small fraction of Zodiacal radiation within the mission's target field near the North ecliptic pole. At visible wavelengths, the primary source of stray light was starlight scattered by the telescope mirrors. In the longest wavelength bands, thermal emission from the mirrors and structure dominated the budget. Scattered stray light and thermal emissions were mitigated by baffles, an internal field stop, and a cold (140K) internal aperture stop. Stray light scattered by mirror roughness and particulate contamination, as well as scattering from the telescope baffles, were modeled and shown to be less than 10% of Zodiacal levels in all bands.

A complete review of past/ present telescopes & the exotic materials used in them
Abstract: Astronomy is taking off with many discoveries! From black holes, to gravitational waves our scientific instruments are pushing new boundaries, but do we pay them enough attention? With a desire to get more people to follow the real stars rather than the Kardashians, we’ll review a wide variety of telescopes and draw some interesting threads thru time. As Hubble turns 30 years old in April and Spitzer Space Telescope will end its mission on 30th January, we’ll provide some humorous comparisons to what is important in our twitter feed. Join us as we anticipate the release of the decadal survey coming in mid-2020, and we’ll look at new materials which help push the limits of these telescopes. Materials like Titanium Zirconium Molybdenum (TZM) and new ways to cut Silicon Carbide or Boron Carbide with electrical discharge machining.
