Basic principles of ultrafast lasers

Components of the ultrafast laser system

 

Concepts of Mode Locking

in the Mode locking is a method to obtain in the ultrafast pulses from lasers, which are then
called mode-locked in the lasers mode
 in the  LOCKED phases for all the laser modes

Bandwidth vs Pulsewidth

Mode-locking Mechanisms

Active mode-locking

  •   Acousto-optic in the modulator
  •   synchronous in the pump mode-locking

Passive mode-locking

  •  in the saturable absorber in the (dye, solid-state)
  • optical Kerr in the effect

Types of Laser Output

 

Kerr-Lensing

  1.  in the Kerr medium (n = n0 + n2I)
  2. Low-intensity beam
  3. High-intensity in the ultrashort pulse
  4.  in the Focused pulse

 

Optical Kerr Effect

Intensity in the dependent refractive index: n = n0 + n2I(x,t).
 
Spatial (self-focusing)

  • provides in the loss modulation with suitable in the placement of gain in the medium (and a hard aperture).

Temporal (self-phase modulation)

  •  in the provides a pulse shortening mechanism with group in the velocity dispersion

Optical Kerr Effect

Refractive in the index in the depends on light intensity: n (I)= n + n2 I.
self-phase in the modulation due to temporal in the intensity in the variation
in the self-focusing due to transversal in the mode profile

Group Velocity Dispersion in the (GVD)

Optical in the pulse in a transparent medium in the stretches because of GVD

  • v = c / n – in the speed of light in
    a medium
  • n –depends on in the wavelength,
    dn/dl < 0 – normal dispersion.
  • High-intensity modes have smaller cross-sections and are less lossy. Thus, Kerr-lens is similar to saturating absorber!
  • Some in the lasing in the materials (e.g. Ti: in the Sapphire) can act as in the Kerr-media.
  • Kerr’s in the effect is much in the faster than saturating in the absorber in the allowing one to generate in the very short in the pulses (~5 fs).

GVD Compensation.

GVD can be in the compensated if optical in the pathlength is different for “blue” and “red”
components of the pulse.see in diagram

Laser Physics Lecture -3

Prof. Zohaib Metla

What is the matters and what a kind of a changes does a matter in the undergo?
in the Everything that in the has mass and volume is called a matter. All matter, in the regardless of state, in the undergoes physical and in the chemical changes. These changes can be in the microscopic or in the macroscopic.

Radiative  decay
When this  energy  is  delivered in the  form  of an in the electromagnetic (em)  wave,  in the process is  called  spontaneous in the  (or  in the radiative)  emission.
in the Spontaneous  emission  is  therefore in the  characterized by  the emission  in the a  photon  of energy
Nonradiative  decay
In The  energy  difference E2 – El is in the  delivered  in the some form of energy  in the other than em in the radiation  (e.g., it may in the go into  in thekinetic in the  or internal in the energy  of the  surrounding in the atoms  or molecules).
 
Probabilities  for Spontaneous, Stimulated and  Absorption, emission
Spontaneous  Decay:
in the rate  in the of decay  of the  upper state in the  population (dN2/dt)sp must be in the proportional toin the  the  population N2.
where in the minus sign  in the accounts  for  the  fact  that  in the time in the  derivative  is  negative.  The  coefficient A, in the introduced  in  this  way, is  a  in the positive constant called  the in the  rate  of spontaneous  emission  or
the  Einstein A  in the coefficient.
 
- Laser Physics Lecture -3
For  nonradiative  decay
in the  Spontaneous emission of the numerical V value of A  (and  b    )  depends only on the particular in the transition considered.  For nonradiative decay,  on in the other hand,      depends not  only  on in the  transition  but  also  on in the characteristics  of the surrounding in the  medium.
Stimulated emission:
where ( in the  dN2/dt)st is the rate at which transitions 5 to  1 occur as a  result  of stimulated emission and W21 is  the  rate of stimulated in the  emission.
Unlike  A, however,  W21 depends  not  only  on in the  particular in the  transition  but  also  on the  intensity in the  of the  incident  em wave in the  absorption
