Abstract
A light-emitting device, includes: an emitter sealed with a gas emitting light caused by a microwave; a high frequency power supply section including a diamond SAW oscillator and outputting a high frequency signal being output from the diamond SAW oscillator to a subsequent stage; and a waveguide unit emitting the high frequency signal being input from the high frequency power supply section towards the emitter as the microwave.
Claims7
A light-emitting device, comprising:
- an emitter sealed with a gas that emits light caused by a microwave;
