In some examples, a laser-based ophthalmological surgical system (hereinafter “system”) includes a therapeutic radiation source configured to emit therapeutic radiation at a first intensity during a therapeutic portion and to emit probe radiation with a second intensity which is less than the first intensity during a probe portion. The system may also include one or more optical elements configured to direct the therapeutic portion and the probe portion into an eye of a patient and to collect reflected radiation from the eye of the patient. The reflected radiation may be indicative of dynamics of microbubbles in the cells of the eye of the patient.
