Brewster Window
Brewster window, named after Scottish physicist Sir David Brewster, is a type of optical window that is commonly used in scientific and industrial applications.
Are 405nm Lasers Dangerous?
Many people are unaware of the dangers that these devices can pose, particularly when it comes to 405nm lasers. Let’s settle this question once and for all: Are 405nm lasers dangerous?
What does HR and OC Mirror Mean?
Both HR and OC mirrors are essential components in the operation of a laser. The HR mirror reflects the laser beam back into the cavity, where it is amplified by the laser medium and passed through the OC mirror. The OC mirror then allows a portion of the amplified laser beam to exit the cavity, producing the desired laser output.
What is a HeCd Laser?
A helium cadmium laser, also known as a HeCd laser, is a type of gas laser that uses a mixture of helium and cadmium gases as the active laser medium.
Raman Spectroscopy
Raman spectroscopy is a scientific technique that is used to study the vibrational, rotational, and other low-frequency modes in a system.
CO2 Lasers
CO2 lasers are the most commonly used type of laser in industry and are used in a variety of applications including cutting, welding, and engraving.
Ultraviolet Fluorescence with 405nm Lasers
405nm lasers are a type of near ultraviolet (UV) laser that can be used to excite fluorescence in a wide range of molecules. When this type of laser light is shone on certain materials, they will emit light at a different wavelength in a process known as fluorescence.
Diffraction Grating
A diffraction grating is a type of optical device that is used to separate light into its different wavelengths.
What is coherence length and how is it measured?
Coherence length is a term used in optics to describe the length over which two or more waves remain correlated, or “in phase,” with one another.
Dichroic Filters
A dichroic filter is a type of optical filter that is designed to selectively transmit or reflect specific wavelengths of light.
