The liquid ejection apparatus comprises: a nozzle which ejects liquid; a pressure chamber which is connected to the nozzle and filled with the liquid to be ejected from the nozzle; an actuator which causes the liquid to be ejected from the nozzle by applying a pressure change to the liquid inside the pressure chamber, by changing volume of the pressure chamber; and a drive signal generating device which generates a drive signal for driving the actuator, wherein the drive signal includes: a first pull drive waveform component which drives the actuator to increase the volume of the pressure chamber; a push drive waveform component which drives the actuator to reduce the volume of the pressure chamber by a first volume change amount after the first pull drive waveform component, so as to push out a column of the liquid from the nozzle; and a second pull drive waveform component which drives the actuator to again increase the volume of the pressure chamber by a second volume change amount after the push drive waveform component, so as to sever the column of the liquid, an absolute value of the second volume change amount being not less than an absolute value of the first volume change amount.

A semiconductor laser includes an active layer having a light-emitting region of striped structure. A cladding layer is formed on the active layer. Another cladding layer is formed under the active layer. The active layer is interposed between the cladding layer and the another cladding layer. Facets are formed on both ends of a stripe of the light-emitting region in which a part of light emitted radiated, and the remaining light is reflected and amplified. The semiconductor laser includes a means for having a minimum value of a coherence in a range between 2 mW and 7 mW of output of a light radiated from one of the facets which is a light output, and for preventing a phenomenon in which the output is reduced in a range at most 25 mW in accordance with an increase of the current, varied by a variation of a current applied to the active layer.
