Abstract
A laser assembly is provided that includes a laser pump chamber that emits a first light through a laser cavity at a first wavelength, and a polarization assembly that receives the first light and converts the first light into a pulsed light that includes the first light at the first wavelength and a first polarization. The laser assembly also includes a second light at the first wavelength and a second polarization.

A laser assembly comprising:
- a laser pump chamber that emits a first light through a laser cavity at a first wavelength;
- and
- a polarization assembly that receives the first light and converts the first light into a pulsed light that includes the first light at the first wavelength and a first polarization, and a second light at the first wavelength and a second polarization.
An optoacoustic probe for optoacoustic imaging of a volume, the optoacoustic probe having a distal end operable to contact the volume and a proximal end, the optoacoustic probe comprising:
- a laser assembly configured to generate a pulsed light that includes a first light at a first wavelength and a first polarization, and a second light at the first wavelength and a second polarization along a light path to generate optoacoustic return signals when the light reacts with the volume;
- a transducer assembly including a transducer configured to receive the optoacoustic return signals and an acoustic lens provided over the transducer.
An optoacoustic probe for optoacoustic imaging of a volume, the optoacoustic probe having a distal end operable to contact the volume and a proximal end, the optoacoustic probe comprising:
- a laser assembly configured to generate a pulsed light at less than 200 microseconds between pulses along a light path to generate optoacoustic return signals when the light reacts with the volume, the laser assembly including a polarization assembly that receives a first light and converts the first light into the pulsed light, the pulsed light including the first light at a first wavelength and a first polarization, and a second light at the first wavelength and a second polarization;
- a transducer assembly including a transducer configured to receive the optoacoustic return signals and an acoustic lens provided over the transducer.
