A quasi-cw laser source is a type of laser that generates a continuous wave of light with a relatively long pulse duration compared to other lasers. These lasers are often used in scientific and industrial applications where a stable, continuous beam of light is required.
What is it?
Quasi-CW lasers differ from traditional continuous wave (CW) lasers in that they have a slightly longer pulse duration, typically on the order of microseconds or milliseconds. This longer pulse duration allows for a more stable and consistent output of light, making them ideal for applications that require a steady beam of light over an extended period of time.
One of the primary advantages of quasi-CW lasers is their ability to produce a beam of light with a high degree of spatial and temporal coherence. This means that the light waves are all in phase with one another and are highly directional, resulting in a beam of light that is both highly focused and highly collimated. This makes them ideal for a wide range of applications, including laser scanning, laser printing, and laser machining.
There are several different types of quasi-CW lasers, including solid-state lasers, fiber lasers, and gas lasers.
Solid-state Lasers
It is the most common type of quasi-CW laser and is made from solid materials such as crystals or glasses. They are highly efficient and have a long lifetime, making them a popular choice for many applications.
Fiber Lasers
A type of quasi-CW laser that use fibers to guide the light and generate the laser beam. These lasers are highly efficient and are often used in high-power applications such as cutting and welding.
Gas Lasers
These are the third type of quasi-CW laser and are made from gases such as helium, neon, or argon. These lasers are highly efficient and are often used in applications where a high-power beam is required.
In summary, quasi-CW laser sources are a type of laser that generates a continuous wave of light with a relatively long pulse duration. They are highly efficient, reliable, and ideal for a wide range of scientific and industrial applications due to their high degree of spatial and temporal coherence.
