We make use of
unique robotic solutions like robot arms to angle the laser incidence on your
object. This ensures 6 degrees of freedom in up/down, left/right,
forward/backward, and the 3 rotation axis: pitch, yaw, roll. This allows us to
incident the laser at unique angles for non-standard shapes!
Pipes to be cut
at 45 degree angle, and to have odd shapes cut from the sides!
Ultrafast pulse width Laser Applications
We are now
exploring to make laser machines using ultrafast pulses.
For long pulse
(nanosecond duration) laser machining, the energy is deposited over a relatively
long period of time, allowing heat to be conducted into the material and cause
undesirable effects such as splatter and re-solidification of melted material,
discoloration, cracks, and voids due to thermal stress. The size of the “Heat
Affected Zone” (HAZ) limits the minimum feature size that can be created.
For ultrashort
pulse laser processing (pulse durations of 10-12 seconds and below), the
duration of the laser pulse is shorter than the time required for energy to be
transferred to the surrounding area of the laser interaction volume, or
transferred from electrons to atoms, when the initial incident light is absorbed
by electrons. This minimizes the HAZ and maximizes the precision of the material
processing.
This allows us to do very precise
micromachining shown in the pictures below. Inquire our ultrafast laser sources

Electro Optical Q-switches Pockels Cell
A
Pockels cell alters the polarization state of light passing through it when an
applied voltage induces birefringence changes in an electro-optic crystal such
as KD*P and BBO. When used in conjunction with polarizers, these cells can
function as optical switches, or laser Q-switches. Frequently, Q-switches are
employed in laser cavities for the purpose of shortening the output pulse,
resulting in a light beam with enhanced peak intensity. High-speed electronic
drivers properly matched to the cell produce the best results for short pulse
applications.
Nowadays, many laser applications demand faster and faster repetition rates.
Acousto-Optical Q-switches offer rise time of hundreds of nanoseconds, but
Electro Optics can offer rise times of 1ns only! Basically, Electro-optics can
do everything Acousto-optics can do, but much faster!
There are different crystal materials such as KD*P, KTP, RTP, BBO, LiNb03 etc.
for different wavelength of operation.
