Kind Code:
B2
Abstract:
PURPOSE: To provide single mode pulse color laser emission by using short and high Q which emits COM in a vertical mode spread over color gain band width. CONSTITUTION: A mirror M1 is fixed to a member 21 by an O-ring seal 22, and a mirror M2 is mounted on collar 23 mounted on a diaphragm 24. The outer edge of the diaphragm 24 is mounted on the member 21 and a cavity between the mirrors M1 and M2 is sealed. Paths 25 and 26 are provided so as to permit color solution to flow through the cavity. The mirror M2 is mounted on a bent mounting member 27 fixed by the member 21, using a tube 28 whose length can be adjusted. An interval L between the mirrors M1 and M2 is adjusted by the length of the tube 28. The reflectance of the mirrors is selected so as to provide the cavity having high Q for light with a laser wavelength of the color. The mirror M2 is selected to provide high permeability with pumping radiation wavelength. Thus, single mode pulse color laser emission is provided.
