A master's degree in medical physics can potentially lead to a PhD in laser physics, though acceptance may depend on the specific research interests and background of the applicant. While a medical physics program typically prepares students for clinical roles, it may also provide foundational knowledge in laser physics. Prospective PhD candidates are encouraged to reach out to professors whose research aligns with their interests, as this can provide insight into suitability and application procedures. Although transitioning from medical physics to laser physics is possible, pursuing a master's in laser physics might enhance acceptance chances for a PhD. Many students in medical physics programs tend to remain in that field due to better career prospects compared to other physics subfields.
