Visible laser diodes for printing

 

The utilization of visible laser diodes for laser printing is discussed. First, the characteristics of a multiple-element array of single-mode, individually-addressed red (AlGaInP) laser diodes is described. The benefit of shorter-wavelength blue lasers is then evaluated. Finally, towards the realization of a blue laser diode, we describe results for AlGaInN and its heterostructures, which have been grown by OMVPE and characterized, including electrical injection and optical pumping of InGaN-AlGaN heterostructures.
