What Is a Laser Oscillator?
A laser oscillator is a system that emits laser light. A laser is a coherent light with excellent directional and monochromatic properties. A laser oscillator consists of a medium, an excitation source, and a resonance mirror. Together, these three components are called resonators.
Depending on the medium used in the oscillator, there are different types of lasers: gas lasers, solid-state lasers, liquid lasers, semiconductor lasers, and fiber lasers. There are three types of light emission methods: CW (continuous wave) oscillation, pulsed oscillation, and Q-SW (Q-switched) pulsed oscillation.
Uses of Laser Oscillators
Lasers are used in a variety of applications, from military applications to consumer applications such as home appliances. Lasers are used for various purposes based on their output, wavelength, and other characteristics. Lasers are used in the following situations
- Medical care: LASIK and treatment of retinal detachment in ophthalmology, removal of spots and birthmarks in dermatology, etc.
- Electrical appliances: Laser pointers, bar code scanners, optical drives for CDs and DVDs, etc.
- Industrial equipment: laser processing machines used for drilling, cutting, engraving, welding, etc.
In other scientific fields, lasers are used in a wide range of applications, such as lightwave rangefinders for measuring distance, non-destructive testing to inspect surface and internal damage without contact by shining light on it, LIDER to measure distance to distant objects, and laser nuclear fusion.
Principles of Laser Oscillators
Laser oscillators consists of an excitation source (lamp or laser semiconductor) and a resonator (the part that increases the optical intensity). The resonator consists of the laser medium (solid material such as gas or crystal) and a resonance mirror. The structure inside the resonator is as follows: The excitation source is positioned so that it can irradiate the laser medium, and the resonance mirror is placed between the medium from both sides. One of these mirrors is a partial transmissive mirror and the other is a total reflective mirror, and the functions of the two mirrors are different.
When the excitation source is irradiated to the medium, atoms (or molecules) in the laser medium are excited to a high-energy state and emit light as they return to their ground state. Furthermore, when an atom or molecule in the excited state is irradiated with light of a specific wavelength, light is emitted in proportion to the intensity of the light. This phenomenon is called induced emission. When this emitted light is reflected by the resonance mirror and returned to the laser medium, further light is induced and the light is further enhanced. This back-and-forth process is repeated many times, and when the light reaches a certain intensity, it is emitted as laser light from the semi-transmissive mirror.
