BLUE-GREEN COLOR LASER OSCILLATING METHOD, LASER ELEMENT AND BLUE-GREEN COLOR LASER GENERATING DEVICE ADOPTING THE METHOD

摘要

PURPOSE: To achieve compact configuration and mass production of laser elements by utilizing the principle for obtaining blue-green color laser light, after exiting the electrons of a second element to a second energy level by using the photoacoustic energy obtained after the electrons of the first element have been excited to a first energy level as an exciting source. ;CONSTITUTION: When intense exciting light is applied from the outside on the electrons of a base energy level E₀, the electrons of a first element are excited and transfer to a first excited level E₁. Photoacoustic energy is obtained by energy absorption in the falling process to a lower ground energy level E₀. The electrons of the ground energy level E₀ of second atoms, to which this energy is transmitted, floats up to a high second exited energy level E₂. The blue-green color optical energy is discharged during the falling to a lower energy state again. This principle is utilized, and a compact configuration and mass production of the laser elements can be achieved.;COPYRIGHT: (C)1996,JPO
