Source sentences:
text: Beams can only be combined if they are coherent with each other.
text: Alternatively, it is possible to combine the beams of LDs with slightly different wavelengths using dichroic mirrors (→ spectral beam combining).
text: Such beams can be combined actively or passively.
text: The beams from multiple diodes can also be combined by coupling each diode into an optical fiber, which is placed precisely over the diode (but behind the micro-lens).
