The green laser pointer company is specialized in all kinds of gift and
four-in-one green laser pointer .General understanding), ultrashort pulse
compression techniques (general understanding of the general knowledge of
ultrashort light pulses focused by a high peak when the transmission of
ultrashort light pulses in the medium, when the transmission of ultrashort light
pulses in the medium power density, high peak power density, therefore, the
transfer process usually show nonlinear effects, such as self-phase modulation
effect, self-focusing effect, the light sensor birefringence effect and other
effects, such as self-phase modulation effect focusing effect, the light sensor
such as birefringence effect in these nonlinear effects, the nonlinear effects
of the refractive index is the most basic of these nonlinear effects, the
nonlinear effect of the refractive index is the most basic is the additional
refractive index change caused by the optical field, is the additional
refractive index change due to light field, it is determined by the optical
pulse envelope function of time, therefore, taking into account the nonlinear
refractive index effect, a function of time, green laser pointer company owns
an employee team with high quality. therefore, take into account the nonlinear
effects of the refractive index, light pulses in different parts of the
refractive index change caused by (1) faster when the n2 relaxation time Tr is
much lower than the pulse width τp τp << Tr is much lower than the pulse
width τ is a transient response process can be written as: This is a transient
response, △ n (t) can be written as: can be written as △ n (t) = n2 is caused by
I (t) pulse of all parts of the additional phase change: Pulse all parts of the
additional phase changes as follows: k is the wave vector, L is the light pulse
in the length of the transmission medium.
