  2. Laser level - Wikipedia

    en.wikipedia.org/wiki/Laser_level

    The concept of a laser level has been around since at least the early 1970s, [2] the original spinning-mirror design laser plane and line level was patented by the late 1980s, [3] and the compact lens-based laser line level (as produced by many tool manufacturers today) was patented in the late 1990s. It was invented by Oscar Soliz in the late ...

    Laser level – control tool consisting of a laser beam projector that can be affixed to a tripod, and which projects a fixed red or green beam along the horizontal and/or vertical axis. A rotary laser level is a more advanced laser level in that it spins the beam of light fast enough to give the effect of a complete 360 degree horizontal or ...

  4. Level (optical instrument) - Wikipedia

    en.wikipedia.org/wiki/Level_(optical_instrument)

    The Y level or wye level is the oldest and bulkiest of the older style optical instruments. A low-powered telescope is placed in a pair of clamp mounts, and the instrument then leveled using a spirit level, which is mounted parallel to the main telescope. The term dumpy level (also builder's level) endures despite the evolution in design. They ...

  5. Levelling - Wikipedia

    en.wikipedia.org/wiki/Levelling

    Turning is a term used when referring to moving the level to take an elevation shot from a different location. To "turn" the level, one must first take a reading and record the elevation of the point the rod is located on. While the rod is being kept in exactly the same location, the level is moved to a new location where the rod is still visible.

  6. Ring laser gyroscope - Wikipedia

    en.wikipedia.org/wiki/Ring_laser_gyroscope

    A ring laser gyroscope (RLG) consists of a ring laser having two independent counter-propagating resonant modes over the same path; the difference in phase is used to detect rotation. It operates on the principle of the Sagnac effect which shifts the nulls of the internal standing wave pattern in response to angular rotation.

  7. Population inversion - Wikipedia

    en.wikipedia.org/wiki/Population_inversion

    From level 4, the atoms again decay by a fast, non-radiative transition Ra into the level 3. Since the lifetime of the laser transition L is long compared to that of Ra (τ 32 ≫ τ 43), a population accumulates in level 3 (the upper laser level), which may relax by spontaneous or stimulated emission into level 2 (the lower laser level).

  8. Optical isolator - Wikipedia

    en.wikipedia.org/wiki/Optical_isolator

    Optical isolator for laser experiments. An optical isolator, or optical diode, is an optical component which allows the transmission of light in only one direction.It is typically used to prevent unwanted feedback into an optical oscillator, such as a laser cavity.

  9. Laser line level - Wikipedia

    en.wikipedia.org/wiki/Laser_line_level

    A laser line level is a tool combining a spirit level and/or plumb bob with a laser to display an accurately horizontal or vertical illuminated line on a surface the laser line level is laid against. Laser line levels are used wherever accurate verticals and horizontals are required, typically in the construction and cabinetry industries. Some ...
