Green lasers for projector applications need to have not only outstanding beam characteristics but also a high optical performance in order to deliver sharp and bright images. Although a projector also needs red and blue lasers, green is the crucial color in RGB solutions – and also the color that poses the greatest challenges in production. PLT3 520D continues Osram’s success story with green lasers. At 140 mW it achieves an unprecedented high pulse output for direct green laser diodes. In addition, the efficiency of the laser has been increased to a typical value of 8%. Thanks to these improvements, it is now possible to turn a smartphone into a small cinema projector. The small display of the device can be enlarged several times over.
