What is a Laser?
A laser is a device capable of emitting laser light. It works by exciting a beammaterial (such as a gas, solid, or liquid) to an excited energy level, and then using optical feedback to form a highly uniform, focused, monochromatic laser beam in this material. Lasers are used in a wide range of fields, including scientific research, medicine, industry, military and entertainment.
Types of Lasers
Lasers can be divided into various types according to different physical principles, application fields and wavelength ranges, mainly including the following categories:
1.Gas laser: Using gas as the working medium, such as carbon dioxide laser, nitrogen neon laser, argon ion laser, etc.
2.Solid laser: Using solid materials as the working medium, such as Nd: YAG laser, titanium gem laser, sapphire laser, etc.
3.Semiconductor laser: Using semiconductor materials as the working medium, such as laser diode, vertical external cavity surface emission laser.
4.ber laser, fiber amplifier, etc.
5.Free electron laser: Using free electron beam as the working medium, such as free electron laser, free electron self-discharge laser, etc.
6.Optical laser: Using optical materials as working medium, such as photoacoustic laser, optical parametric oscillator, etc.
7.Ultrafast laser: laser with very short pulse width, such as femtosecond laser, picosecond laser, etc.
It is understood that the current domestic femtosecond laser has not been industrialized.

What are the Applications of CoreMorrow Piezo Nanomotion Products in Lasers?
The Main Spare Parts of CoreMorrow Piezo Ceramic Nano-motion Products that Can be Used in the Lasers are as Follows:
1.Tuner, Wavelength Control and Vibration Realization of Laser Resonator
CoreMorrow piezo ceramic product can be used as the driving element of the tuner, and the frequency tuning of the laser can be achieved by adjusting the length of the resonant cavity through the change of voltage.
The piezo ceramic thickness can be controlled by applying voltage to change the optical path length in the laser, thus achieving accurate wavelength control.
CoreMorrow piezo ceramic can also be used as the mirror driver of the laser to adjust the optical path reflection, so as to achieve laser oscillation and amplification.
2.Laser Pulse Controller
Piezo ceramic products can be used as the driving element of the pulse controller to control the output pulse width and interval time of the laser through the change of voltage.
3.Ultra-fast Optical Modulation and Mdulation Itensity
The deformation rate of piezo ceramics can reach nanosecond level, which makes it suitable for high speed optical modulation, such as optical path stabilization and codec for laser communication. By applying voltage, the piezoelectric ceramics can be deformed to a small degree, so that the laser intensity can be modulated and the laser optical modulation can be realized.
4.Laser Optical Lens Driver
5.Q Switching Devices in Solid Lasers
Including Nd: YAG laser, Nd:YVO4 laser, Nd:YLF laser, Ti:sapphire laser, Er: YAG laser, CO2 laser, etc. In addition, piezo ceramics can also be used in acousto-optical Q-modulating devices and Q-modulating devices in other lasers.
CoreMorrow piezo ceramic can be used not only inside the laser, but also cooperatewith the laser.
For example, in experiments to study the properties of matter through light, or experiments on the interaction of light with matter, different lasers are selected according to different substances.
When adjusting the optical path delay, CoreMorrow piezo linear stage can be used to generate 100mm travel, providing conditions for the optical delay.
When adjusting the laser focus of the laser output, CoreMorrow piezo objective positioner can be used, which has the precision of nano-level z-direction adjustment.
In short, piezo ceramic products are widely used in laser and matching laser, which can help laser to achieve high efficiency, precision and stable performance.
