The number the width and the spacing of the emitters are dependent on the manufacturer.
Laser diode bars.
The relative value of the emitting areas in the active layer with respect to the bar width is called filling factor ff.
Wavelengths include 780 830nm 880nm 915 980nm 1060nm and 1400 1500nm.
And coherent continues to push forward with ongoing advances in power brightness efficiency and divergence.
Diode bars are high power semiconductor lasers laser diodes containing a one dimensional array of broad area emitters or alternatively of subarrays containing 10 20 narrow stripes.
Laser diode bars and stacks.
High power diode laser bars for pumping and direct diode applications.
Ceos laser diode bars are offered on over 200 packages designs with multiple wavelength options available.
In a bar the individual emitting areas emitters lie side by side and together with the non emitting areas between the emitters they form the so called active layer.
