Abstract: An apparatus for a polymerase chain reaction (PCR) diagnosis includes a transmitter that includes a multi-wavelength light source outputting a first light source signal and a second light source signal, which have different wavelengths, and that applies the first light source signal and the second light source signal to a DNA sample, a code generator that generates a first code signal and a second code signal corresponding to the first light source signal and the second light source signal, respectively, a delay controller that generates a first delay signal and a second delay signal corresponding to the first code signal and the second code signal, respectively, and a receiver that compares the first and second fluorescent signals emitted from the DNA sample with the first and second delay signals, and accumulatively integrates the first fluorescent signal or the second fluorescent signal based on the comparison result.

Abstract: A femtosecond pulse laser apparatus includes a pump light source configured to provide a pump light, a gain medium configured to obtain a gain of a laser light using the pump light, a first curved mirror and a second curved mirror, which are provided at both sides of the gain medium, an output mirror configured to transmit a portion of the laser light and reflect the other portion of the laser light to the gain medium, a mode locking portion configured to generate a femtosecond pulse of the laser light, and an acoustic wave generator configured to provide an acoustic wave into the gain medium so as to adjust self-phase modulation of the laser light.

Abstract: Disclosed is a femtosecond laser device. The femtosecond laser device includes a pulse oscillator configured to generate a laser pulse, a pulse width stretcher configured to stretch a width of the laser pulse, a pulse width compressor connected to the pulse width stretcher to compress the width of the laser pulse, a pulse amplifier disposed between the pulse width compressor and the pulse width stretcher to amplifier an intensity of the laser pulse, and a nonlinear pulse attenuator including an optical fiber connected between the pulse width amplifier and the pulse width stretcher and deformed to have a spiral shape, a stretched length, or a twist.
