Key Differences
Consider that "lazer" with a "z" looks more casual and less scientific.
Visualize a "laser beam," and remember that beams follow scientific rules, including correct spelling.
Use word association: "Laser" rhymes with "razor," which is also spelled with an "s."
Remember that "Laser" is an acronym, so each letter stands for a specific word in the full term.
Think of "ser" at the end to remind you it's related to "Stimulated Emission of Radiation."

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word "laser" is an acronym for "light amplification by stimulated emission of radiation".
Any of several devices that emit highly amplified and coherent radiation of one or more discrete wavelengths. One of the most common lasers makes use of atoms in a metastable energy state, which, as they decay to a lower energy level, stimulate others to decay, resulting in a cascade of emitted radiation.
A beam of radiation emitted by a laser.
(Sports)A ball or puck sent in a straight line at high speed
Shot a laser into the upper right corner of the goal.
A device that produces a monochromatic, coherent beam of light.
A beam of light produced by such a device; a laser beam.
A laser printer.
A gum resin obtained from certain umbelliferous plants.
Such a plant.
To cut with a laser.
(sports) To throw or kick with laser-like precision.
A device which produces an intense, usually narrow, monochromatic beam of coherent light; called also optical maser. It has various forms, and is used in various applications in science and technology. The beam is produced by boosting the majority of the electrons in specific radiation-absorbing atoms in a medium into a higher energy level, from which they are stimulated by their own emitted radiation to drop back synchronously to their lower energy level, and emit light which is in phase (coherent).
An acronym for light amplification by stimulated emission of radiation; an optical device that produces an intense monochromatic beam of coherent light
