Abstract
The present disclosure generally relates to systems and methods for laser power measurement, and more particularly, systems and methods for laser power measurement in a sterile operating environment. In certain embodiments described herein, power measurement is performed utilizing two laser sources: 1) a first laser source configured to generate a first laser beam (treatment laser); and 2) a second laser source configured to generate a second laser beam (test laser). The first laser beam generates a bubble in a test material (e.g., water, saline, balanced salt solution, gel, etc.) and the second laser beam is reflected back with the reflected portion of the second laser beam being measured to determine a lifetime of the bubble and correlate the lifetime measurement with a power measurement based on a correlation curve.
