Outer cavity type tunable laser system of micro ectromechanic component array of corner prism surface

Abstract

An adjustable laser system of external cavity type is prepared as emitting a light beam by light source, setting a grating in front of light source for reflecting light beam to be the first reflection beam, setting angular mirror array in front said grating to receive the first reflection beam and to reflect out the second reflection beam, forming the third reflection beam by using said grating to reflect the second reflection beam and using receiver to the third reflection beam, combining light reflection function of angular mirror array with light switch to let said laser system have function of wavelength adjustment.

Description

[0001] This application is a divisional application of the invention patent application No. 200410028650.3 filed on March 4, 2004. technical field [0002] The invention relates to an adjustable laser system, in particular to an adjustable laser system using a corner mirror array. Background technique [0003] Micro-electromechanical system (MEMS) has been widely valued since the late 1980s; it is a general term for integrated micro-components or systems, and furthermore, it includes the use of IC-compatible batch processing technology to manufacture Electronic and mechanical parts; and the size of the manufactured components or systems is as small as microns and the largest does not exceed millimeters.

Problems solved by technology

However, in the traditional chamfered incidence external cavity tunable laser system, in order to achieve the effect of tunable wavelength, the structure of the laser system will need optical elements with shading effect, such as the aforementioned I-shaped plate or It is a V-shaped plate, which will complicate the organization of the entire laser system and is not suitable for all current trends that emphasize lightness and compactness; therefore, how to make the system architecture more streamlined without affecting the efficacy of wavelength modulation It has become the focus of improving the application scope of the angle-cutting incident external cavity adjustable laser system

However, at present, in order to make the incident light reflect parallel to the original path, most of the reflectors currently used are a combination of a vertical mirror and a horizontal mirror. However, currently available reflectors on the market Although the mirror combination emphasizes that the angle accuracy between the vertical mirror surface and the horizontal mirror surface is 90°+0.08°, this error range (+0.08°) is undoubtedly a major limitation affecting the efficiency of the instrument in all micro-electromechanical fields that emphasize precision and ingenuity. Factor, therefore, how to improve the verticality of the mirror combination is also a major research topic of the semiconductor laser system
