Inventor: KONDO MASAKI
IPC: G02F1/37
Filed: 2002-11-08
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that not only the control of output variation of incident light but also the control of variation of pulse width of the incident light are needed in order to make peak output after a wavelength conversion constant, since the peak output after the wavelength conversion is in proportion to the square of a peak output of the incident light.  <P>SOLUTION: This wavelength conversion device is so constituted that an oscillation wavelength of a beam emitted from a laser oscillator oscillating in a short pulse of a nanosecond or below is converted into a short wavelength by a non-linear optical element. The wavelength conversion device has a first attenuator controlling output of the laser oscillator, two prism pairs, a first aperture having a fixed size so that a specified wavelength can be selected from the laser beam passed through a first prism pair of the two prism pairs and having a wavelength spectrum showing a spatial distribution, a condenser lens condensing the laser beam passed through the two prism pairs, the non-linear optical element making the wavelength of the condensed beam short and a lens parallelizing the condensed laser beam.  <P>COPYRIGHT: (C)2004,JPO
