Abstract
An optical intersatellite link transmitter which uses a high-power laser diode (LD) amplifier so as to simultaneously achieve a high output power, fast frequency response, and good beam profile, is presented. Calculated results indicate that a good beam profile could be achieved with a travelling-wave type broad area LD amplifier when an input beam is focused just in front of the input facet of the LD amplifier. It is also shown that optical output power is controllable as a parameter of the injection current to the LD amplifier.
