Letter from the Chair

Dear members of DLS,

We hope this letter finds you and your families well, but we also recognize that it is impossible for any of us to escape the horrific consequences of the continuing pandemic and political upheaval in the world. We offer our condolences for any losses you may have experienced and, along with the APS, we condemn the Russian invasion of Ukraine.  If you would like to learn more about the APS response to the war visit: https://aps.org/programs/international/ukraine.cfm .  

It is my pleasure to serve the Laser Science community as DLS chair and to thank the past chair Randy Bartels for his excellent work in this role before me.  This newsletter looks back to 2021 thanks to our newsletter editor, Samir Bali, to ensure our APS fellows, Schawlow Prize winners, travel grant recipients, undergraduate symposium participants and others are celebrated and documented. Congratulations to all for the excellent work and vitality you bring to Laser Science!

The various awards and programs offered by DLS continue to exist thanks to the efforts of the people of the APS and would not be possible without a demonstrated need from the community as measured by our DLS membership numbers.  Today, we are making a specific request to all of you to help increase the membership of DLS; please encourage colleagues and students to join or renew their membership in the DLS.  We also ask you to consider giving of your time, for example, by running for office, starting a new APS student chapter or volunteering to organize a poster competition.   Please contact me, or Sue Dexheimer, the Chair-Elect, if you are interested in offering ideas to make DLS more effective or learning of ways to help.

Yours sincerely,

David A Reis,
DLS Chair 2021-22

DLS Symposium on Undergraduate Research, 2020 and 2021

The twentieth annual DLS Symposium on Undergraduate Research at the APS LS conference was held remotely on Monday, 14 September, 2020, and the twenty-first symposium was held remotely as well on Monday, 1 November, 2021. The remote format meant that the presentations in both years were entirely oral: there were no poster sessions. The talks were all given by students reporting on projects they performed at about 50 universities or research institutes.

The Symposium talks were run in two parallel sessions starting at 11 am EST (to accommodate presenters and participants on the West coast) and ending at 6:30 pm. In both years the Symposium concluded with a special presentation given by Dr. Brad Conrad who is the National Director of the Society of Physics Students and Sigma Pi Sigma. He provided advice on graduate schools, career trajectories, and multiple other personal topics of great interest to the students.

The total number of presentations in both years had to be limited to 48 (10 min + 2 min for Q&A). There were several second authors to some submissions, so the total number of student participants was 57 in 2020 and 61 in 2021. In 2020 twenty-three presenters were female, an impressive representation of almost 40%. In 2021 there were as many as thirty female presenters, an unprecedented representation of nearly 50%. These Symposia have brought over 800 students to our annual meetings to present what are often the first research papers of their budding careers.

Session presiders during 2020 were: Herman Batelaan (Univ. Nebraska), Eric Borguet (Temple Univ.), Amy Sullivan (Univ. CO), Michael (Middlebury College), Irina Novikova (College of William and Mary), Catherine Herne (SUNY New Paltz), Nathan Lindquist (Bethel Univ.), and Klaus Bartschat (Drake Univ.)

Session presiders during 2021 were: Eric Jones (Stony Brook), Hong Lin (Bates), Seth Aubin (William and Mary), Nathan Lindquist (Bethel), Michael Durst (Middlebury), Jenny Magnes (Vassar), Catherine Herne (SUNY New Paltz)

Students commented: “Even though the conference was remote, it benefited me in multiple ways. I gained experience giving a scientific presentation and exposure to other research in optical physics. I attended all the talks in my session which were really interesting because I could learn about research being conducted at other universities. Also, I attended the career insights special event. Both presenters’ stories were helpful because they gave great advice about pursuing a career path in physics research and how it's not always a straightforward journey.”

“This was my first time presenting research at a conference so it was a great learning experience, and I was really impressed by the projects other undergrads have been working on. I loved the career talk by Dr. William Phillips and Dr. Elsa Gamire; they shared several useful pieces of advice which will stay with me. Additionally, I attended the keynote by Dr. Nargis Malvalvala and Dr. Mikhail Lukin (at the Quantum 2.0 conference). All in all, it was great and I hope to go back and watch some of the recorded sessions.”

“….. This was the first time I have had the chance to do so, and I am extremely grateful for everything you did to provide this chance.”

“It gave me a lot to look forward to in my research this summer and early fall. I always get pretty nervous presenting my own work, so it was actually pretty helpful to be able to present virtually, where I couldn't see everyone I was talking to. Listening to research other people have done is also really enlightening, especially when they're doing similar research, so I'm able to better understand what they are talking about.”

“Preparing for the Symposium was a great opportunity to consider my research outside of the context of my lab group and reflect on why it might be of interest to other young researchers. Watching other undergraduate talks allowed me to appreciate and better understand the variety and creativity of research in optical physics, as well as the connections between my work and what others are investigating. I also found the regular programming spectacular and enjoyed watching five or six talks from accomplished researchers. The virtual format and the recording of sessions made it quite easy and convenient to join different sessions and offered me an ability to see great speakers that I wouldn't have otherwise.”

The remote format eliminated most costs: the only expense in both years was the registration fee that was handled by DLS. The OSA meetings department provided technical support for the online session management. The remote Symposia in 2020 and 2021 were organized and arranged by Harold Metcalf, Stony Brook University, and Samir Bali, Miami University.

Distinguished Traveling Lecturer Program 2022

The DTL program was established in 1992 to bring distinguished scientists to predominantly undergraduate colleges and universities in order to convey the excitement of Laser Science to undergraduate students. In 2001 it was expanded to include graduate schools. Priority is given to those institutions that are not located in major metropolitan centers and do not have extensive resources to bring in outside speakers.

During 2021 in-person visits by DTL’s were suspended owing to the pandemic, although zoom meetings were still offered. Fortunately, we are now able to resume in-person visits. Usually, lecturers visit selected academic institutions for two days, during which time they give a public lecture open to the entire academic community and meet informally with students and faculty. The DTL may also give guest lectures in classes related to Laser Science. Applications to host a DTL should be submitted by members of DLS. The DLS pays an honorarium. The host institution takes care of any local expenses.

For a list of available speakers, see the DTL homepage at https://engage.aps.org/dls/resources/traveling-lecturer

The DTL program committee is chaired by David Reis.
