wavelengths as standard options▶ <10 ns pulse duration at 1064 nm▶ Electro-optical Q-switching▶ Turn-key operation

BENEFITS▶ Continuous tuning of repetition

rate while maintaining constantpulse energy, superior beam
pointing and energy stability
make the laser the first choice formicromachining, marking, thin film
removing applications▶ Close to Gaussian smooth beamprofile with low value M² < 1.3
and good focusability is beneficial
for such applications, as LCD andOLED display repair▶ Compactness and lightness make alaser easy transportable, saves on
valuable laboratory space

NL200 series DPSS air-coolednanosecond lasers offer high pulse
energy at kHz repetition rates.
End-pumped design makes thislaser compact and easy to integrate
into various laser equipment bothindustrial and R&D. Featuring
short nanosecond pulse duration,
variable repetition rate and external
TTL triggering, nanosecond diodepumped NL200 series Q-switchedlasers are excellent and cost-effective
sources for specific applications, whenhigher pulse energy is required, likematerial processing, LCD and OLED28

▶ Fast wavelength selection is superior

for applications where alternating
wavelengths are required, likematerial ablation, LIBS

▶ Air cooling, cheap and reliable

end-pumping technology, amplifiers
free DPSS design guarantee easy
operation and alignment of laser,
simple installation and low life-timeownership cost

▶ Rugged sealed cavity▶ Compact size

▶ Simple and robust▶ Air cooled▶ External TTL triggering▶ Remote control via keypad

and/or any controller runningon any OS using REST APIcommands▶ Variety of control interfaces USB,

RS232, LAN, WLAN ensure easy
control and integration of laser
with laboratory or OEM equipment

display panel repair, ablation, marking,engraving, laser cleaning, laser
deposition and many more.
This laser can be equipped withharmonic generation modules for532 nm, 355 nm, 266 nm and 213 nm
wavelengths. Excellent energy stability
and a wide range of wavelength
options make this laser a perfecttool for spectroscopy, photoacoustic
imaging and remote sensing
applications. The mechanically stable
and hermetically sealed design
ensures reliable operation and long
lifetime of the laser components.

Due to continuous improvement, allspecifications are subject to change.
Parameters marked typical are illustrative;
they are indications of typical performanceand will vary with each unit we manufacture.
Unless stated otherwise all specifications aremeasured at 1064 nm and maximal pulse
repetition rate and for basic system withoutoptions.

Please indicate clearly if 1064 nm output
is required in case harmonics options areordered (except H200STHC module). In sucha case, the energy of 1064 nm is optimized
for harmonics generation and may differ fromspecified in the table.
Unless stated otherwise all specifications aremeasured at 2500 Hz pulse repetition rate.
Unless stated otherwise all specifications aremeasured at 1000 Hz pulse repetition rate.
