Abstract
There are disclosed a converging device for converging a light having a high aspect ratio, and a light source module, a laser device and an optical signal amplifier using such converging device. A converging device has a converging portion for converging a light. The converging portion has an incident surface, a tip portion and a reflective surface for reflecting the light so that the light is transmitted toward the tip portion. The converging device has a guide portion provided in the reflective surface along a direction from the incident surface to the tip portion. The light transmitted in the converging portion is introduced to the guide portion and the light in the guide portion is reflected so as to be transmitted toward one end of the guide portion. The converged light is emitted from the tip portion or an end of the guide portion.
