Q-SWITCH

KD*P (Potassium Dideuterium Phosphate) is the most widely used material for
electro-optical applications due to its excellent E-O properties.
An electro-optic material such as KD*P can alter the polarization
state of light passing through it, when an applied voltage
induces birefringence change in the crystal.
When used in conjunction with polarizers,
the KD*P pockels cell can function as optical
Q-switch to generate laser pulses. KD*P is
used for applications from UV up to around

LASER OPTICS

Thin film polarizer

Nd:YAG

Nd:YAG crystal rod, with 1064nm wavelength, is used in laser marking and other laser equipment.
Such as military, medical, industrial and other fields. It is the only solid substances
that can work continuously at room temperature, and is the most excellent performance laser crystal.
Also it is widely used as a solid-state laser materials. YAGrod’s role is to generate a laser,
with the partial and full reflect mirror on both ends,
YAG rod can produce a stable and continuous laser,
it is the core part of YAGand fiber laser.
Advantage of Nd YAGRod
○ High gain
○ Low threshold
○ High efficiency
○ High optical quality
○ Low loss
○ Large mechanical strength
○ Good thermal conductivity and thermal shock characteristics

Er:YAG

Er: YAG is a kind of excellent 2.94μm laser crystal, widely used in laser medical system
and other fields. Er: YAGcrystal laser is the most important material of 3nm laser,
and the slope with high efficiency, can work at room temperature laser,
laser wavelength is within the scope of the human eye safety band, etc.
2.94 mm Er:YAG laser has been widely used in medical field surgery,
skin beauty, dental treatment.
Advantages of Er:YAGCrystal
○ High slope efficiency
○ Operate well at room temperature
○ Operate in a relatively eye-safe wavelength range,etc.

Cr4+:YAG

Cr4+:YAG (Y3Al5O12) is an ideal material for passive Q-switching of Nd:YAG and
other Nd and Yb doped lasers in the wavelength range of 0.8 to 1.2um.It is superior
stability and reliability, long service life and high damage threshold.
Advantages of Cr4+:YAG
○ High chemical stability and reliability
○ Being easy to be operated
○ High damage threshold (>500MW/cm2)
○ As high power, solid state and compact passive Q-Switch
○ Long life time and good thermal conductivity,etc.
