A modulated laser is a laser whose output intensity, frequency, or phase is varied in a controlled manner to encode information, typically for communication or signal processing applications. Modulation can be achieved through various techniques, such as amplitude modulation (AM), frequency modulation (FM), or phase modulation (PM). This allows the laser to transmit data over distances, making it essential in fields like fiber-optic communication, medical devices, and industrial applications. The modulation enables efficient and high-speed data transmission while maintaining signal integrity.
What else can I help you with?
Is Frequency modulated in the light beam of the laser when transfering sound?
Yes it is. That is why you get a scrachy and unclear sound.
What has the author Barbara Blind written?
Barbara Blind has written: 'Response of two-level atoms to intense amplitude modulated laser beams' -- subject(s): Laser beams, Atoms
What are the applications of junction lasers?
Applications of junction lasers are in terms of laser output beams as information carriers. Since this output beam needed to be modulated in terms of intensity, the junction laser is handy. The junction laser supplies regulated current.
What is a source of digital light?
Light is not naturally digital - perhaps you mean solid state? Digital light as in a fibre-optic cable is just laser light modulated.
What has the author Robert Edward Rowlands written?
Robert Edward Rowlands has written: 'A sequentially modulated ruby laser system for transmitted and scattered light dynamic photoelasticity'
What does am and fm?
fm- frequency modulated am- amplitude modulated
What does a m mean in radio language?
AM = amplitude modulated. FM = frequency modulated.
A two cavity klystron tube is a?
a. velocity modulated tube b. frequency modulated tube c. Amplitude modulated tube d. simple triode
What is FM means frequency modulated or fast modulated?
FM means Frequency Modulation.
When a carrier is phase modulated with an integrated modulating signal the resultant is?
It gives frequency modulated signal
What does AM and FM mean?
am is amplitude modulation, fm, frequency modulation
Why analog data have to be modulated onto an analog signal?
For transmission through a radiowave.
