Abstract:
A variable-wavelength light source is provided with a first laser medium, a first optical resonator constituted of a total reflection mirror and a half-mirror, a second laser medium, a second optical resonator constituted of a total reflection mirror and the half-mirror, a first filter having a pair of first mirrors configured to cause first light and second light to be transmitted and reflected selectively, a second filter having a pair of second mirrors configured to cause the first light and the second light to be transmitted and reflected selectively, a first drive mechanism configured to operate the first mirror and the second mirror in conjunction with each other, and a second drive mechanism configured to operate the second mirror.
