Description
Technical field
The present invention relates to semiconductor laser field, more particularly to it is a kind of based on VCSEL laser diodes composition
Manual variable optical systems and its method.
Background technology
The past during the decade, in field of semiconductor lasers, the edge-emission semiconductor laser based on GaAs materials is always
Dominant position is occupied, and is widely used in the fields such as industry, medical treatment, scientific research.However, but there is it in edge-emission semiconductor laser
The defects of fatal, although its life expectancy is up to tens thousand of hours, edge-emitting laser because one is single-point laser light source,
Corresponding technical requirements can not all be reached completely in terms of thermal conductivity transmission and its laser eye safety, because its heat conductivility does not reach
The reason for being worked under 60 degree of environment above, or causing permanent failure after work, causes application field to be limited；Simultaneously because it is adopted
With single-point laser light source, add the technology that direct current generator rotates by means of frosted glass in terms of optics homogenizes processing, it is possible to cause
Electromechanics fails, and has dry point after beam homogenization, so as to influence beam quality, furthermore, because it increases its material（Direct current generator
Or frosted glass）Make 5-10 times that cost is this product, accordingly, it is desirable to provide a kind of new semiconductor available for industrial circle swashs
Light device.

Row projects in epitaxial wafer direction from the edge of reaction zone.
Edge-emission semiconductor laser and VCSEL have following features respectively：Edge-emission semiconductor laser is linear light
Source, because its light beam in process of production by lens compresses its angle, it is in the angle of divergence both vertically and horizontally
Greatly (for vertical direction full-shape about at 60~70 degree or so, horizontal direction full-shape is about at 7~10 degree or so, in 10 for difference：1 light
Beam rectangular profile), and spike distribution is presented in its far field light intensity；And VCSEL is sphere shape light, the smaller (hair of its angle of divergence
It is about 22 degree or so to dissipate angle full-shape), its far field light intensity approximation flat-top distribution, Energy distribution is evenly.Therefore, partly led with edge emitting
Body laser is compared, and evenly, and Gaussian Energy Distribution is uniform on far field objects thing for the light of VCSEL transmittings.In addition, with
The advantages of edge-emission semiconductor laser is compared, and VCSEL also has other, such as：With higher operating temperature, it is contemplated that the longevity
Order that longer and fault rate is low, degradation shows that the theoretical life-span of VCSEL laser diodes has reached 50000 hours, and can
So that using planar package, packaging technology requires lower.However, due to traditional VCSEL because relatively low opto-electronic conversion is imitated
Rate and higher production cost, it is set never to obtain excessive concern in market competition.
With advances in technology, VCSEL gradually realizes the high-power output close to edge-emission semiconductor laser, together
When due to its unique structure, its apply present in plurality of advantages, such as high reliability, high temperature resistant, uniform optical distribution, resistance to
Adverse circumstances etc..Furthermore multiple spot LASER Light Source will be may require that due to the progress of its existing industrial technology, in market to be applied to
Gesture identification, recognition of face, 3D sensings etc., it will bring a brand-new revolution to VCSEL laser fields.It is but existing
