SMALL PICO-SECOND LASER AND ANALYZER USING SAME

摘要

PROBLEM TO BE SOLVED: To provide a small size and low price pico-second laser which may be directly varied in wavelength at the ultraviolet ray region, and also to provide an analyzer using the same pico-second laser.;SOLUTION: The analyzer uses the pico-second laser which is formed as a distribution feedback type dye laser which can generate the laser beam by superimposing the ±primary diffracted light beam on a dye cell and resistive to the energy of 1mJ or more. In addition, the same pico-second laser includes a blaze-free transparent type diffraction grating in which ≥100 stripes/mm (pitch: ≤10 μm) of a metal thin film are formed on a quartz plate with a lithography process.;COPYRIGHT: (C)2005,JPO&NCIPI
