Our work spans continuous-wave and femtosecond solid-state laser systems, light–matter interaction studies, custom instrumentation, and numerical modeling of photonic systems. We integrate advanced optical design with hands-on engineering, from 3D-printed optomechanics to home-built diagnostic tools.
The Cal Poly Photon Lab welcomes students from all backgrounds and experiences, fostering an environment where every member feels respected, supported, and empowered to contribute fully to our research and learning community. Interested students are encouraged to contact Dr. Isinsu Baylam Toker for research opportunities.
CW and Femtosecond Ti:Sapphire Lasers
Development of continuous-wave and femtosecond Ti:sapphire lasers pumped by high-power blue diodes and frequency-doubled green lasers. This project also includes the construction of a home-built autocorrelator for measuring femtosecond pulses.
1064 nm-Pumped Infrared Lasers
Design and development of infrared solid-state lasers pumped by high-power 1064 nm sources, with applications in broadband near-infrared generation and nonlinear optics.
Computational Photonics and Laser Design
Using MATLAB, Mathematica, and Python to model laser resonators, predict beam dynamics, and optimize system performance.
Light-Matter Interaction
Experimental investigation of light-matter interactions in a range of materials, with applications in chemistry and material science. Current capabilities include a UV-VIS spectrophotometer and a nanosecond pump-probe measurement system operating at visible wavelengths.
Controller and Cooling Units for High-Power Laser Diodes
Design and implementation of electronic control systems and thermal management solutions for high-power infrared laser diodes.
3D-Printed Optomechanics
Design and fabrication of custom optomechanical components using 3D printing, including design and fabrication of integrated cooling units and mounts. Our lab uses a Creality K1 Max 3D printer with a 300 *300*300 mm build volume.
AI-Assisted Optimization of Solid-State Lasers (upcoming)
Future work will investigate intelligent, data-driven methods for optimizing laser operation and performance.
