Seal-355-3/5 User manual
Please read this manual carefully before attempting to install, operate the laser.
This user manual details all health and safety issues regarding the safe installation,
operation. For safety and laser performance setting, please aware the laser hazard
information and operational Instructions.
The laser enclosure is not allowed to open, maintenance and service only can be done
at JPT factory, upgrade could be done on site when technical support presence.
Without JPT factory permit, customer open the laser enclosure will void the warranty.
Laser wavelength 355nm （not visible ）， average power>3W/5W （peak
power >7500W/20000W ）， categorise as IV laser ，contact with direct, reflect or
scattered laser radiation can Cause serious damage to the eyes, human tissue please
wear laser safety glass when operate the laser.
Flammable, explosive items and black paper, cloth, leather not allowed in light path.
Caution：even only turn on pilot beam, still with weak UV laser emission

1 Product tour and technical parameter
1.1 Product overview
Compare with IR laser, the UV laser process is direct break the object chemical bond,
The process generate much less heat to minimize thermal effect, processed material turn
to Atom level，reduce contamination to the environment. The feature of UV laser is short in
wavelength, Small spot size, intense energy, high solution, it's good for precision marking,
narrow line width Requirement, high quality marking, less thermal effect, also with long term
stability. Widely used in micro machining, micro hole drilling, cutting, scribing, already apply
to many Material like metal, semiconductor material, ceramic, glass and polymer.
JPT made Seal-355-3/5 series UV laser are end pump solid state laser. Stable and compact
resonator design makes higher laser efficiency, good beam quality and high stability. Long
lifetime and maintenance free. The chamber inner LD design, reduced the fiber interference.
The new design of AIO, it’s space saving and has a stronger anti-interference capability.
Seal-355-3/5S is a member of Seal family. The laser of this series has excellent beam quality (M2
< 1.2) and perfect spot characteristics (circularity>90%). The whole machine adopts an
integrated structure design, which combines the optical and external driving circuit, making the
product series have strong anti-interference ability. Optimize and upgrade the fully sealed
structure to effectively prevent the entry of external dust. At the same time, the isolation of
external water molecules makes the whole machine have a strong anti-moisture characteristics,
making the Seal series can adapt more harsh industrial environments. In addition, the service
life can be greatly prolonged by introducing a self-cleaning system for intracavity As an
upgraded version of Seal-355-3/5, the output laser of Seal-355-3/5S series ultraviolet solid-state
lasers has very short pulse width (<10ns@60KHZ) and excellent pulse stability (<3%
RMS@60KHZ) at medium and high repetition frequencies.
