In particular, the case where semiconductor laser chip 110, the angle θ for being configured to configure multiple multi-emitting figures become smaller
Under, the collimation lens 102 long using multiple focal lengths is needed, therefore unit scale becomes very big.
The above subject in the semiconductor laser chip 100 of single-shot beam type it can also happen that.That is, the above subject is such as
Generation is equally possible in lower situation: in order to make the output of semiconductor laser chip 100 rise and make the width of emitter 101
The case where broadening, the semiconductor laser chip 100 for configuring multiple single-shot beam types simultaneously make from multiple semiconductor laser chips
100 light shafts projected the situation incident to a collimation lens 102.
