Laser system for an optoacoustic probe

A method for imagining a volume using an optoacoustic probe comprising:

• supplying a constant voltage from a power supply to a first capacitor bank having a first flash lamp that emits a first light along a light pathway upon reaching a first determined charge state;
• providing a first closed loop feedback using a first setpoint that is a first voltage that is less than the constant voltage;
• wherein the first determined charge time is based on the first setpoint;
• and
• carrying the first light along the light pathway to an optical window of the optoacoustic probe.

A laser system for an optoacoustic probe comprising:

• a power supply configured to provide a constant voltage;
• a first capacitor bank coupled to the power supply to receive the constant voltage and configured to supply power to a corresponding first flash lamp upon reaching a first determined charge state of the first capacitor bank;
• the first capacitor bank including a first closed loop feedback configured with a first setpoint that determines a first charge time for the first determined charge state;
• and
• wherein the first setpoint has a first voltage that is less than the constant voltage.
