LaserLock is a copy restriction system for CD-ROMs with 32-bit Windows applications introduced by MLS LaserLock International Inc. in 1995. LaserLock...

Mode locking is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds...

Munich demonstrated the smallest mode locking laser capable of emitting pairs of phase-locked picosecond laser pulses with a repetition frequency up to...

(apart from the dither motor assembly (see further description below), and laser-lock), compared to the conventional spinning gyroscope. This means there is...

used to bypass copy protection schemes such as SecuROM, SafeDisc and LaserLock. In order to copy the CD, the user may have to copy the disc on another...

The LaserDisc (LD) is a home video format and the first commercial optical disc storage medium, initially licensed, sold and marketed as MCA DiscoVision...

operation of copies of discs with advanced protection (SafeDisc, SecuRom and LaserLock, CDCOPS, StarForce and Protect CD), which are used on some discs with...

Locked-in syndrome (LIS), also known as pseudocoma, is a condition in which a patient is aware but cannot move or communicate verbally due to complete...

irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates. At high laser flux, the material...

Laser medicine is the use of lasers in medical diagnosis, treatments, or therapies, such as laser photodynamic therapy, photorejuvenation, and laser surgery...

backscattering causing the beams to synchronise and lock together. This is known as a lock-in, or laser-lock. The result is that there is no change in the interference...

laser is a laser that uses a gain medium that is a solid, rather than a liquid as in dye lasers or a gas as in gas lasers. Semiconductor-based lasers...

A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form...

A blue laser emits electromagnetic radiation with a wavelength between 400 and 500 nanometers, which the human eye sees in the visible spectrum as blue...

Laser linewidth is the spectral linewidth of a laser beam. Two of the most distinctive characteristics of laser emission are spatial coherence and spectral...

Laser surgery is a type of surgery that uses a laser (in contrast to using a scalpel) to cut tissue. Types of surgical lasers include carbon dioxide,...

Laser science or laser physics is a branch of optics that describes the theory and practice of lasers.[citation needed] Laser science is principally concerned...

A fiber laser (or fibre laser in Commonwealth English) is a laser in which the active gain medium is an optical fiber doped with rare-earth elements such...

solid-state laser (DPSSL) is a solid-state laser made by pumping a solid gain medium, for example, a ruby or a neodymium-doped YAG crystal, with a laser diode...

A chemical laser is a laser that obtains its energy from a chemical reaction. Chemical lasers can reach continuous wave output with power reaching to megawatt...
