The gain switching effect in semiconductor laser diodes can be technically used to generate laser pulses of less than 100 ps by means of a fast driver circuit with a pulse generator integrated on the chip. With this new technology, the resolution and range of TOF applications can be improved or innovative applications for lasers in medical technology can be developed, for example, in opto-acoustic diagnostic procedures such as elastography imaging. For TOF applications, a synchronization output has also been integrated on the chip so that the pulse generator and detector can be perfectly synchronized. Central prerequisites for such applications are precise scaling of the current pulse, which can be set with a resolution of 1 ps, and temperature stabilization. This is the only way to avoid secondary pulses at pulse repetition frequencies of up to 200 MHz. The high pulse power combined with low average power is suitable for comparatively long ranges and for applications where eye safety must be taken into account.
