[Overview] [Problem to be Solved] To make it possible to generate pulsed laser light having a stable polarization direction while suppressing an increase in the pulse width of the pulsed laser light and a decrease in the peak intensity of the pulsed laser light, and miniaturizing an optical resonator and a laser device in a case where an amorphous material is used as the base material of a laser medium. [Solution] There is provided a passive Q-switch pulse laser device including: a laser medium; and a saturable absorber.

The polarizing element has different reflectances with respect to the respective pieces of emission light in polarization directions orthogonal to each other.

An optical fibre assembly (10) disposed within a catheter (12) for ablating mammalian, such as heart tissue. The optical fibre assembly has a plurality of optical cores (16A-16C), each core defining a leading end and a trailing end and being adapted to carry an optical imaging beam. An optical lens arrangement (25) is operatively connected to the leading end of the plurality of optical cores for causing divergence of the light beams emitted therefrom. The optical fibre assembly (10) creates a field of view by directing a plurality of said optical imaging beams onto a tissue portion and capturing a reflected portion of said beams.
