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.
Laser diode bars.
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.
And coherent continues to push forward with ongoing advances in power brightness efficiency and divergence.
Coherent unmounted bars have set the standard for high reliability in real world applications.
Ceos laser diode bars are offered on over 200 packages designs with multiple wavelength options available.
Wavelengths include 780 830nm 880nm 915 980nm 1060nm and 1400 1500nm.
The number the width and the spacing of the emitters are dependent on the manufacturer.
They typically contain between 20 and 50 emitters each being e g.
High power diode laser bars for pumping and direct diode applications.
