The number the width and the spacing of the emitters are dependent on the manufacturer.
Laser diode bars.
High power diode laser bars for pumping and direct diode applications.
Coherent unmounted bars have set the standard for high reliability in real world applications.
The relative value of the emitting areas in the active layer with respect to the bar width is called filling factor ff.
Ceos laser diode bars are offered on over 200 packages designs with multiple wavelength options available.
Laser diode bars and stacks.
Proudly offers diode laser packaged bars vertical arrays stacked laser diode arrays and horizontal arrays linear laser diode arrays at wavelengths ranging from 808nm to 1100nm with high output power up to 6000w in cw and qcw operation mode and different package cooling methodologies.
Wavelengths include 780 830nm 880nm 915 980nm 1060nm and 1400 1500nm.
They typically contain between 20 and 50 emitters each being e g.
