Photonics Dictionary: L

A process used in the design, repair and customization of integrated circuits. A low-power laser etches a silicon wafer placed inside a gas-filled vacuum chamber, initiating a chemical reaction.

A pump-probe technique whereby a single wavelength source may be used in order to excite a given sample to determine electronic transitions.

Laser-induced fluorescence (LIF) is a spectroscopic technique that involves using a laser to excite molecules or atoms, leading to their emission of fluorescence light. This technique is widely used...

The laser damage threshold refers to the maximum level of laser intensity that a material can withstand without experiencing damage. It is a critical parameter in laser applications and is...

Visible laser radiation, often optically expanded and collimated, used to induced temporary blindness from within a walking distance of an impending target. Laser dazzle systems may be in a handheld...

Device that operates by interaction of incident radiation with semiconductor based material in order to produce an electrical signal or by other means, to interact with calorimetric devices which...

Laser peening is a surface enhancement technique used to improve the mechanical properties of materials, particularly metals. It involves the use of high-energy laser pulses to generate shockwaves on...

A plasma produced by the interaction of an intense laser pulse with a material surface. Production of ionized particle with high intensity radiation. The narrow path of the intense field produces a...

Laser-mediated gene transfer refers to a technique in molecular biology and genetic engineering that utilizes lasers to introduce genetic material into cells. This method is a type of gene delivery...
