Abstract

A narrowband laser apparatus may be provided with a laser resonator including optical elements for narrowing a spectral linewidth, a spectrometer configured to detect spectral intensity distributions of multiple pulses included in a pulsed laser beam output from the laser resonator, a spectral waveform producer configured to produce a spectral waveform by adding up the spectral intensity distributions of the multiple pulses, a device function storage configured to store a device function of the spectrometer, a wavelength frequency function generator configured to generate a wavelength frequency function which represents a frequency distribution of center wavelengths of the multiple pulses, and a deconvolution processor configured to perform deconvolution processing on the spectral waveform with the device function and the wavelength frequency function.
