• The conditions for optimizing laser feedback in small optical pick-ups using 660 nm strained quantum well laser diodes are discussed. Peaks in the coherence function occurring as a periodic function of the feedback path length are found to diminish rapidly once high frequency drive current modulation is applied. However, feedback path lengths less than 25 mm still show large values. This coherent feedback makes the laser sensitive to variations in the phase of the feedback light. The choice of the feedback path length is critical to eliminating these effects.
