Title:
集光部品並びにこれを用いた光源モジュール、レーザー装置及び光信号増幅装置
Document Type and Number:
Japanese Patent JP4471522
Kind Code:
B2
Abstract:
There are disclosed a converging device (10) 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 (10) has a converging portion for converging a light. The converging portion has an incident surface (12a), a tip portion and a reflective surface (12b) for reflecting the light so that the light is transmitted toward the tip portion. The converging device (10) has a guide portion (14) provided in the reflective surface (12b) along a direction from the incident surface (12a) to the tip portion. The light transmitted in the converging portion is introduced to the guide portion (14) and the light in the guide portion (14) is reflected so as to be transmitted toward one end of the guide portion (14). The converged light is emitted from the tip portion or an end of the guide portion (14).
