The QLF1335-xx series are 1300nm Quantum Dot laser diodes intended for use in extremely high temperature environments and are capable of operation at up to 200°C ambient without cooling.
The use of QDL's proprietary Quantum Dot technology in the active layers of these Fabry-Perot (FP) laser diodes results in reduced temperature sensitivity and enables higher temperature operation and lower power consumption than conventional laser diodes.
The plot to the right shows the LI curves for the QLF1335-AD device which is rated for operation at ambient temperatures up to 175°C. It can clearly be seen that the laser is well within the linear operating region at its rated 2mW and 175°C. Thermally driven rollover occurs at 4.5mW and 180°C. Conventional laser diodes cannot approach this level of performance.
