Abstract
A laser generation apparatus includes a light source making oscillate a laser having a frequency based on the amount of current applied thereto, a splitter ramifying a laser incident thereon at a preset ratio, an interference system receiving the ramified laser, generating an interference signal by ramifying a laser incident thereon, and measuring the phase of a laser oscillated, a temperature adjustment unit uniformly maintaining a temperature of a part of the interference system, an error integrator receiving a signal that has undergone the interference system and accumulating a phase error occurred, a phase error detection unit detecting a phase difference between the signal of the error integrator and an offset current value, a driving driver applying a current to the light source, and a control unit controlling an operation of each component and controlling the driving driver based on results of the detection of the phase error detection unit.
