Laser irradiating device

A laser irradiating device comprising:

• a reflector having a receiving space formed therein;
• a flash lamp inserted and mounted in the reflector to generate light;
• a laser rod for resonating light incident from the flash lamp to emit a laser;
• a capacitor for storing, for a predetermined time, voltage to be supplied to the flash lamp;
• a digital variable resistor unit for outputting different voltages according to set resistance values;
• a voltage increasing unit for increasing voltage input from the digital variable resistor unit and supplying the increased voltage to the capacitor;
• a control unit storing resistance values corresponding to laser irradiating levels and setting a resistance value of the digital variable resistor unit, as a resistance value corresponding to the set laser irradiating level, when the laser irradiating level is set by a user;
• and
• a trigger circuit unit turned on by the user's manipulation to supply a charge voltage of the capacitor to the flash lamp.
