Summer colloquium series // Improving beam quality in high power broad-area lasers

We are concluding our Summer Colloquium Series this coming Monday, with Jose Perez Romero giving his talk on “Improving beam quality in high power broad-area lasers”. There will be free pizza! Hope to see you there.

When: Monday, August 29, 12 pm
Where: Wilmot 116

Abstract: Filamentation hinders beam quality in high power broad-area diode lasers. This talk will review some of the nonlinear mechanisms that cause this filamentation, as well as techniques that can overcome the issue in order to improve beam quality.

Summer colloquium series // High-Q microresonator + THz emission

The UR SPIE chapter Summer Student Colloquium Series present Betty Sun and Kang Lui! Check out their abstracts below. Snacks and drinks will be provided courtesy of SPIE and we look forward to seeing you there!

When: Tuesday, August 23, 12:15 pm
Where: Wilmot 116

sun_xuanSpeaker #1: Betty Sun
Title: Suppressing the fundamental thermo-optic noises of a high-Q microresonator
Abstract: We report a novel approach to dramatically suppress the fundamental temperature fluctuations and thermo-optic noises of a high-Q microresonator by orders of magnitude, achieved remarkably via pure optical means without cooling the device temperature.

Title: Study of THz emission from ring-Airy beam induced plasma
Abstract: By using abruptly autofocusing beams, as opposed to the conventional Gaussian beams, to generate plasma in the ambient air, the authors are able to observe an enhancement in the terahertz (THz) wave radiation from the plasma. This work could inspire a new direction for controlling THz radiation from laser-induced plasma by sculpting the excitation beams, and pave the way to THz remote spectroscopy.

Summer colloquium series // 3 axis measurement probe for optical metrology

We will be continuing our Summer ColloquiuButlerm Series this Tuesday, with Sam Butler, whose talk is titled “3 axis measurement probe for optical metrology”.

When: Tuesday, August 2, 12PM
Where: Wilmot 116

As a note, snacks will be provided courtesy of SPIE! Hope to see you there!

Abstract: The burgeoning field of freeform optical design is currently limited by metrological techniques for validating manufactured designs. State-of-the-art measurement systems do not provide the flexibility, measurement bandwidth, or high uncertainty required for producing freeform optics of the same quality achievable for spherical and aspheric parts. One promising avenue for reaching high-quality metrology is through the use of optical coordinate measuring machines (OCMM). These are 5-axis probing machines that use non-contact, optics-based probes for surface measurement. This research seeks to develop an optical probe with high measurement bandwidth and low measurement uncertainty in a compact form factor that provides linear and angular measurement of the optical surface under test. The probe uses homodyne interferometry in a Michelson configuration for linear displacement sensing, and a lens in combination with a position-sensitive detector in an autocollimation capacity for angular displacement sensing. Development of electronics and signal processing, as well as preliminary measurement results using a prototype probe, will be discussed.

We are kicking off our summer colloquium series!

With free pizza, of course.

On Tuesday, June 21st, the UR SPIE student chapter will be kicking off its annual Summer Colloquium series. The first talk of the series has been jointly organized by SPIE and the new student group “Students for Science Advocacy”.

When: Tuesday, June 21, 12pm
Where: B&L 109

Prof. Duncan Moore will discuss the role of a PhD Engineer in the US Senate and White House in the Office of Science and Technology, how to get involved and what is expected of someone in this position.

We look forward to seeing you there! And remember, if you would like to give talk as part of our summer series, you can reach us at urspie@gmail.com. The top two speakers from the series will be awarded with prizes!

Summer colloquium seeking speakers!

It’s that time of the year again! The UR SPIE is gearing up for the Summer Student Colloquium Series!

On Tuesdays throughout the summer, beginning June 21st, we will be having a lunch-hour colloquium series during which one or two students can present their research to their peers. We welcome students in all departments working with light-related technology to present!

Colloquium speakers will have the experience of giving a talk to fellow students and gain insight and feedback on their work. You can even use this as a venue to practice a talk you plan to give at an upcoming conference. In addition, there will be prizes awarded to the top two speakers at the SPIE General Interest Meeting in September!

If you are interested, please send us an email at urspie@gmail.com

Girl Scouts STEM-A-Palooza

On Saturday April 16, UR SPIE Chapter members brought some optics-related demonstrations to the Girl Scouts of Western New York STEM-A-Palooza event! If we had known it would be so sunny, we would have brought more outdoor demos! The FLIR camera and “stained glass” polarization demos were both big hits. Another successful day!
