PURPOSE: A pulse laser generator using Q-switching is provided to operate with less operation power compare to a previous technology as a pulse laser is generated through Q-switching using a variable optical attenuator. CONSTITUTION: A laser generator comprises a total reflection mirror (100), a laser medium part (200), a pump beam part (300) and a variable optical attenuator (400). The total reflection mirror reflects light inputted The laser medium part is equipped with a first terminal which reflects a part of light inputted and which outputs out remainder and laser oscillation is caused receiving pump beam. The variable optical attenuator is connected to the total reflection mirror and a second terminal and the laser oscillation is controlled absorbing light according to a control value. The pump beam part sends the pump beam to the laser medium part.
