Clamping jig for semiconductor laser bars

Abstract

A clamping jig for mounting semiconductor laser bars includes: multiple supporting bars for holding laser bars therebetween; a pair of supporting plates each of which has a mounting face for mounting the supporting bars in a row; a pressing member for pressing the supporting bars for holding the laser bar; pressing cover members for covering both ends of each supporting bar to prevent supporting bars from falling from the supporting plate; and a supporting frame for detachably supporting the supporting plates and pressing cover members. Each supporting bar is formed with a longitudinal length greater than the laser bar, within a predetermined length so as to be mounted within the supporting frame. Both of the pair of supporting plates may be mounted so as to face one another, or just one may be mounted with the pressing cover members being mounted on the supporting frame instead of the other supporting plate.

1 . A clamping jig for mounting semiconductor laser bars formed by cleaving a semiconductor wafer so as to form reflection coating with predetermined reflectivity by vapor deposition or sputtering on a predetermined face thereof, said jig comprising: 
 a plurality of supporting bars for holding said laser bars therebetween;    a pair of supporting plates having a mounting face for mounting said supporting bars in a row;    a pressing member for pressing said supporting bars for holding said laser bars through the supporting faces thereof;    pressing cover members for covering both ends of each supporting bar so as to prevent each supporting bar from falling down from said supporting plate; and    a supporting frame for detachably supporting said supporting plates and pressing cover members;    wherein each supporting bar is formed with a longitudinal length greater than said laser bar, and within a predetermined length so as to be mounted within said supporting frame; and    wherein said pair of supporting plates can be mounted on said supporting frame with said mounting faces facing one another at a predetermined interval,    or wherein only one of said pair of supporting plates can be mounted on said supporting frame, and said pressing cover members instead of the other supporting plate can be mounted on said supporting frame.    
   
   
       2 . A clamping jig for mounting semiconductor laser bars according to  claim 1 , wherein the mounting face of said supporting plate can be inserted within said supporting frame.  
   
   
       3 . A clamping jig for mounting semiconductor laser bars according to  claim 1 , wherein said pressing cover member is formed of a bar-shaped plate member or a rod-shaped member so as to cover one end of each of said semiconductor laser bars at the same time.  
   
   
       4 . A clamping jig for mounting semiconductor laser bars according to  claim 1 , wherein the supporting face of said supporting bar has a smaller width than the width of the electrode-formed face of the laser bar.  
   
   
       5 . A clamping jig for mounting semiconductor laser bars according to  claim 1 , wherein the supporting face of said supporting bar is formed with a coefficient of friction μa equal to or greater than 0.9 μb and equal to or smaller than 1.1 μb, wherein μb represents the coefficient of friction of the surface of said semiconductor laser bar.  
   
   
       6 . A clamping jig for mounting semiconductor laser bars according to  claim 1 , wherein said supporting bar is formed of Si.
