PHYS 4061/5061: Experimental Techniques in Laser Physics
Involves a selection of experiments in laser physics, with emphasis on techniques necessary for trapping neutral atoms with lasers. One lecture hour and one tutorial hour and two three hour laboratory sessions per week. Integrated with: GS/PHYS 5061 3.00.
Students taking this course can expect to use state of the art equipment and gain a working knowledge of conventional experimental techniques in atomic physics and laser spectroscopy. This background should be adequate preparation for working in research laboratories in related fields and industry related to photonics.
Prerequisites:
- SC/PHYS 2211 1.00 and SC/PHYS 2212 1.00, or SC/PHYS 2213 3.00
- SC/PHYS 2020 3.00
- SC/PHYS 2060 3.00
Corequisite:
- SC/PHYS 3040 6.00.

Course Content
Students will be exposed to common a data analysis tutorial (based on Mathematica) during the fIrst two weeks of the term. Subsequently, students will work in groups of two and cycle through 9 experiments related to laser spectroscopy. Since there are 10 groups of two, and only 9 experiments, each group will enjoy one week without performing a laboratory exercise. Note that this does not change the due date for your reports.
Laboratory work will include pre-lab exercises, data analysis, interpretation, and answers to specifIc questions in the manual. Reports do not require extensive written descriptions. Mathematica should be used for all data analysis.
The laboratory component of the course emphasizes experimental techniques related to laser spectroscopy and hands-on skills.
The lecture component introduces theoretical concepts related to instrumentation such as gas lasers, diode lasers, laser beam propagation, Fabry -Perot resonators, electro-optic modulators, acousto-optic modulators and optical detectors.
The tutorials cover theoretical concepts related to laboratory experiments.
Textbook
The principal resource is a comprehensive laboratory manual that can be purchased from the physics department office (Petrie 128).
Abbreviated notes for lectures and tutorials can be obtained from the course web site: http://datamac.phys.yorku.ca/
There is no textbook. A useful list of references is included below.
Lab Reports
The grade for lab reports will be based on attendance and content.
The first lab report is related to the data analysis tutorial that will be completed over three, 3-hour lab sessions. Subsequent experiments will each involve two, 3-hour lab sessions.
The requirements and format for lab reports are clearly specified in the section titled "Format of Lab Reports" in the laboratory manual.
Graduate students are required to complete additional exercises.
Please consult TAs if the requirements are not clear.
The first lab report (on the Mathematica tutorial) requires submission in hardcopy and in electronic format. Part of the grade for this report will depend on the functionality of the Mathematica notebooks that students will submit in electronic form. All other labs require only hard copy submissions.
Due Dates
Pre-lab exercises and lab reports should be submitted to the TAs in PSE 226 by 2:30 PM, at the beginning of lab sessions. Please see specified due dates for lab reports in the Schedule section above.
Lab reports submitted by 4:30 PM on the day after the due date will incur a penalty of 10%. Two days after, a penalty of 25%. Three days or more, a mark of zero will be assigned. Late lab reports can be submitted in the Tuesday lab session, or in Petrie 128.
Exceptions will require the approval of the instructor. Exceptions will be granted only under exceptional circumstances.
TAs will not accept e-mail submission of lab reports.
Graded reports will generally be returned one week after the due date.
Attendance
TAs will record attendance. Students are expected to be present during the entirety of all 3-hour lab sessions or until the laboratory work is completed.
Unless special arrangements are made with the course instructor, students arriving more than 10 minutes after the beginning of a laboratory session will be deemed as being absent.
If a student is absent even for a single lab session or leaves a lab session before the work is completed, the score on the relevant lab report will be zero. If a lab is completed within the 1 st session, TAs can certify that attendance is not required during the 2nd session.
Make-up Labs
Makeup labs are intended to cover situations in which there is equipment malfunction or factors beyond the control of students that prevented the completion of an experiment and in cases where approval from the course instructor is obtained due to medical reasons.
Students missing a lab session due to medical reasons are required to file an attending physician statement with the course instructor (not to be confused with a doctor's note) and demonstrate a convincing reason for absence to schedule a makeup lab. The attending physician's statement can be obtained from the registrar's office.
Students approved for a makeup lab by the course instructor should sign up for a makeup lab with the TAs.
