Mode locking is a technique used in lasers to generate short pulses of light by synchronizing the phases of different longitudinal modes of the laser's optical cavity. This results in the constructive interference of multiple modes, leading to the creation of ultra-short pulses, often in the picosecond or femtosecond range. Mode-locked lasers are widely used in applications such as precision spectroscopy, medical imaging, and telecommunications due to their high peak power and temporal resolution. The technique can be achieved through various methods, including passive and active mode locking.

What is stability mode locking?

Stability mode locking is a technique used in laser systems to achieve a stable and continuous output of ultrafast pulses. By controlling the phase relationship between different modes of the laser cavity, it ensures that these modes reinforce each other, leading to a consistent pulse generation. This approach enhances the reliability of the pulse train and minimizes fluctuations in pulse energy and duration, making it useful for applications in telecommunications, precision measurement, and medical imaging.

Can you use the prl laser cannon on normal mode in resident evil 4?

No, you can not. You have to go through professional mode to get it.


How do you use a laser in defence mode on moshi monsters?

You do not use a laser on Moshi Monsters at all. Moshi Monsters is not a game designed for fighting.


Robotic laser ball wont make music in music mode?

The robotic laser ball moves to music that is being played. It does not actually make its own music. Put it on Music mode and place it near a radio or stereo and there you go!!

What are the applications of PHASE modulation?

Some examples of applications of phase modulators are: * A phase modulator within a laser resonator of a single-frequency laser can be used for wavelength tuning, or for active mode locking (FM mode locking) of a laser. * A phase modulation of a beam with moderate modulation strength is often used in laser frequency stabilization schemes, e.g. with the Pound-Drever-Hall method. * Various kinds of interferometers and setups for spectroscopic measurements require phase modulators, often with a periodic drive signal. * Some metrology applications require frequency combs, generated by sending a single-frequency beam into a phase modulator. In that case, the phase modulation often needs to be strong in order to obtain a large number of optical sidebands. * In data transmitters of optical fiber communication systems, phase modulators can be used for encoding the transmitted information. An example is the method of phase shift keying. Source: http://www.rp-photonics.com/phase_modulators.html

on halo 3 and haloreach when u get in forge u can get a spartan laser make it too were it is about too shoot then turn into the ball when u come back to spartan mode u shoot the laser automatically


Why narrow tube used in He Ne laser?

Why He-Ne tube is narrow ? The resonant cavity's a) cross-sectional dimensions governs Transverse mode b) axial dimensions governs Longitudinal mode c) The desired TEM00 mode (it gives beam of Gaussian-profile, having minimum spread due to diffraction) is obtained by making cross-sectional dimensions just slightly larger than the spot size of the TEM00 mode. d) The coexistence of multiple modes reduces the monochromaticity of the laser.


05 Corolla T2 Rear seat belt locks on and won't free up unless unplugged its ok when I try it out but my wife and mum have had the problem is it possible that it to do with height or size?

If your car is a 1996 or newer, the retractor is usually a SWITCHABLE retractor - meaning that it can switch from the usual mode of locking only in an EMERGENCY, to a mode where it locks at all times - called the AUTOMATIC locking mode. Changing the belt from the EMERGENCY to AUTOMATIC locking modes is easy - simply pull the shoulder belt out all the way (do it slowly) - when you get to the very end, let the belt go back in. As it goes back in you will likely hear a ratcheting sound - and if you give a gentle pull you will notice that the belt is locked and it is not possible to make the belt any longer. In the automatic locking mode, the shoulder belt only gets shorter - it does not get longer (it will however go back to "normal" when you let the belt all the way back in). http://thecarseatlady.wordpress.com/installation-tricks/lockingthebelt/
