A solid-state laser apparatus of the laser diode excitation type includes a condenser mirror to input incident light to a solid laser rod. The condenser mirror has an elliptical shape. In this apparatus, one focus of the mirror is located in a laser beam incident side and the other focus is located in a central axis of a laser rod. In addition, beam axes of beams from laser diodes are fixed to a long axis of the oval condenser mirror.

Solid-state laser apparatus and laser process apparatus

A bottle opener comprises a bomb; a cylindrical body encasing the bomb; a needle mounted on the cylindrical body; a cylinder wherein are disposed an air flow path for guiding the gas released from the bomb to the needle, a piston having a valve for opening and closing the air flow path, a bomb needle for breaking through a gas outlet port of the bomb, and a variety valve; a lid body mounted on the cylinder; a handle pivotably mounted on the lid body for operating the piston; and airtight sealing members for forming airtight seals between the handle, the cylindrical body, the bomb, the piston and the cylinder. The bottle opener can be used a plurality of times with a single bomb and is capable of withstanding use over a long period of time in safe and without leakage.
