Scientific terminology informal or non-technical English, to say "strictly speaking" for "sensu stricto" and "broadly speaking" and so on is valid. Even in formal writing, there is no formal requirement to use the Latin terms rather than the vernacular. Valid reasons for using these Latin or partly Latin expressions are not points of pretentiousness; they include: A good example is the word "laser", an acronym for "Light Amplification by Stimulated Emission of Radiation", and therefore all its letters should be capitalized. However, because of frequent use, this acronym became a neologism, i.e., it has integrated into English and most other languages. Consequently,
Sound amplification by stimulated emission of radiation introduced around 1995 The pumping is created by mechanical oscillations of a cylindrical resonator and the phase bunching of bubbles is realized by acoustic radiation forces. A notable fact is that gas bubbles can only oscillate under an external action, but not spontaneously. According to other proposed schemes, the electrostriction oscillations of the dispersed particle volumes in the cylindrical resonator are realized by an alternating electromagnetic field. However, a SASER scheme with an alternating electric field as the pump has a limitation. A very large amplitude of electric field (up to tens of kV/cm) is required to realize the amplification.
