Description

A kind of high-power semiconductor laser source system with location indicative function

Technical field

The utility model belongs to technical field of laser processing, relates to a kind of semiconductor laser light resource system, can be used in Laser Processing, has location deixis.

Background technology

High-power semiconductor laser has the advantages such as volume is little, lightweight, efficiency is high, the life-span is long, be widely used in Laser Processing, laser medicine, laser display and field of scientific study, become the comprehensive core devices that new century development is fast, achievement is many, subject infiltration is wide, range of application is large.

Laser processing technology is to have merged modern physics, chemistry, computer, material science, the new and high technology of the multidisciplinary technology such as advanced manufacturing technology, comprise Laser Surface Modification Technology, laser surface recovery technique, laser melting and coating technique, laser product technology etc., can make low grade material realize the modification of high-performance top layer, reach the high performance best of breed of part low cost and working surface, bring possibility for solving entirety strengthening with the contradiction that other surface peening means are difficult to overcome, important component material is mated with the selection of performance, design, manufacture and produce important Beneficial Effect, and production efficiency is high, crudy is reliable and stable, cost is low, economic benefit and social benefit are good.High-power semiconductor laser system of processing is non-visible light, more dangerous in the time carrying out laser processing operation, simultaneously in the time of adjusting process because of the invisible difficulty in process that makes.

Utility model content

The above-mentioned defect existing for overcoming background technology, the utility model provides a kind of high-power semiconductor laser source system with location indicative function.

The technical solution of the utility model is as follows:

Have a high-power semiconductor laser source system for location indicative function, comprise semiconductor laser stacks and indication light source, the light naked eyes that this indication light source sends can identifications and are distinguished with the light that semiconductor laser stacks sends; Described semiconductor laser stacks has multiple bar bars, position corresponding to folded battle array middle part bar bar arranges dorsad a speculum in the bright dipping light path of semiconductor laser stacks, described indication light source is positioned at outside semiconductor laser stacks bright dipping light path, the light that sends of indication light source after speculum reflection with laser parallel outgoing.

Based on above-mentioned basic scheme, the utility model also can do following optimization and limit and improve:

Above-mentioned indication light source is red-light source.

Above-mentioned speculum becomes miter angle setting, and the light that indication light source sends is perpendicular to semiconductor laser stacks bright dipping light path.

If a is the spacing (being generally 1.8mm) between the adjacent bar bar of folded battle array, b be single bar bar actual go out optical width; C is the thickness of speculum,

The length l of speculum meets: $\sqrt{2}b\≤l\≤2\sqrt{2}-\sqrt{2}b-c.$

The utlity model has following advantage:

1, the utility model structure is simple and clear, is convenient to fitting operation, only need a speculum that size is minimum be set in bar bar corresponding position, folded battle array middle part, can realize laser spot position indication.

2, because of pilot light with the laser that adds man-hour in same optical axis, processing operation, in out-of-focus appearance (working face at non-focus place), does not affect indication location.

The specific embodiment

As shown in Figure 1, a kind of high-power semiconductor laser source system with location indicative function, comprises semiconductor laser stacks and red-light source (different from common folded paroxysm optical wavelength).Semiconductor laser stacks has multiple bar bars, position corresponding to folded battle array middle part bar bar becomes miter angle that a speculum is set dorsad in the bright dipping light path of semiconductor laser stacks, red-light source is positioned at outside semiconductor laser stacks bright dipping light path, the light that red-light source sends is perpendicular to semiconductor laser stacks bright dipping light path, after reflecting by speculum, ruddiness, on the bright dipping light path light axis of semiconductor laser stacks, can be located semiconductor laser stacks light source.

Because set speculum only only need cover at the area of bar bar corresponding position, middle part and speculum the ruddiness that red-light source sends, reduce as far as possible speculum other are clung to stopping of bar bright dippings, thereby can greatly reduce laser loss at work.
