Classification: CPC G  H | IPC G  H

Claim 0:
1. A light source apparatus used for a flow cytometer, which is configured to cause a plurality of particles to flow in a flow cell in such a manner to follow one after another in a flow cell length direction and to irradiate the plurality of particles with a laser beam from a side of a flow thereof, the light source apparatus for irradiating the particles with the laser beam, comprising:
a semiconductor laser that is configured to emit the laser beam;
a collimating lens that is configured to collimate the laser beam emitted from the semiconductor laser in a spread light state;
a beam conversion unit that is configured to match the flow cell length direction with a slow axis direction of the laser beam collimated by the collimating lens in the flow cell after reducing the beam diameter of the laser beam in a fast axis direction and increasing the beam diameter in the slow axis direction; and
a focusing lens that is configured to focus the laser beam that has passed through the beam conversion unit in the flow cell.
