Abstract:
A semiconductor laser element machining device for machining an end surface of a semiconductor laser element generating and outputting a laser beam, said semiconductor laser element machining device comprising:optical measuring means for measuring an optical characteristic of said laser beam outputted by said semiconductor laser element;machining laser beam output means for focusing a machining laser beam on said end surface of said semiconductor laser element;position adjusting means for adjusting a relative positional relation between said end surface and a position where said machining laser beam is focused; andcontrolling arithmetic means for controlling said machining laser beam output means and said position adjusting means;wherein, using measurement data from said optical measuring means, said controlling arithmetic means causes said machining laser beam to machine said end surface so that said laser beam outputted through said end surface will have an optical characteristic approximating a desired characteristic.
