2 Working Conditions and Cautions
2.1 Laser Safety Cautions
For the safety of yourself and other person, please read this section carefully.
This product will emit laser beam with high intensity and high linearity. The beam is invisible
light with wavelength of 1064nm. Material exposed under the beam will result in temperature
increase and damage of surface structure. According to Standard IEC60825, the hazard
classification of the laser beam from this product is class-4. It is dangerous to observe class-4 laser
beam directly or under mirror reflection.
Please select the protective glasses with the right wavelength rejection!
Please wear the protective glasses properly during operating the product!
The laser beam of the product may cause ocular damage!
Avoid to watch the light source directly!
Avoid exposure of skin and clothes to the laser beam!
It’s forbidden in any case to aim the laser beam to human and
animal!
Prohibit juveniles to touch and operate the laser!
2.2 Working Condition
This product can only work in temperature within 20℃-30℃ and humidity within 20%-70%.
Keep the temperature and the humidity as constant as possible.
The water chiller requirement:
The water pressure: ≥0.4MPa, water temperature: ≤23℃. Cooling capacity:≥1400W.
Water flow:10L/min-16L/min. Temperature control accuracy: ±0.2℃。
Keep the environment to be clean. Don’t expose this product under heavy dust.
The product should be mounted on a stable platform. Intense vibration or dropping may
Gauss Lasers High Power Infrared Picosecond Laser
Gauss Lasers Page 6 of 20 105 Gaoyi Road, Baoshan, Shanghai, China
cause damage.
Do not put any liquid container or any tiny parts close to the product thus to avoid any
unexpected case that liquid and tiny parts may fall into the instrument. If such case happened, shut
down the laser quickly.
2.3 Pay Attentions
The product need about 30 minutes for warming up after power on before ready to use.
Don’t execute working point rescan during this period.
Don’t block ventilation windows of the product so as to avoid heat accumulation inside
the product which will cause failure.
The laser machining result is heavily depending on laser performance and external
optical path. Make sure every mirror or lens is clear, without vibration and degradation.
Please power off the machine and cover the light output port when not using for long
time.
It is forbidden to disassemble and re-assemble the product without formal permission
from Gauss Lasers. Gauss Lasers will not be responsible for any damage caused by such
improper behavior. The warrantee will be automatically ineffective.
Move the instrument carefully. Please keep it from intense vibration and impact.

Refer to section 5.3.2 for more information.
5.3 Control Interface
5.3.1 Control Connector
CN2 and CN4 are TTL compatible, unless other wise noted in the pin description. For interface
designs level ranges of the TTL standard should be taken into consideration.
The cables connect to the control connector should be attached with a magnetic ring to avoid
interference or crosstalk.

The HY12-R04 laser system consists of three operating mode.
⚫ Internal Trigger Mode
⚫ Gate Mode
⚫ PSO Mode
Gauss Lasers High Power Infrared Picosecond Laser
Gauss Lasers Page 18 of 20 105 Gaoyi Road, Baoshan, Shanghai, China
These modes can be changed by GUI and saved to laser system.
5.3.2.1 Internal Trigger Mode
Laser will emit directly after warm up. Laser output power, output frequency and burst
number can be changed by RS-232 interface or GUI.
5.3.2.2 Gate Mode
Laser won’t emit unless GATE signal is valid. Laser output power, output frequency
and burst number can be changed by RS-232 interface or GUI. Timing diagram is as below.
Figure 5-2 Gate Mode Timing Diagram
5.3.2.3 PSO Mode
PSO mode is using the pulse picker to select laser pulse from base laser pulse train.
Timing diagram is as below.
Figure 5-3 PSO Mode Timing Diagram
Base laser output power, output frequency and burst number can be set by RS-232
interface or GUI.
The laser emits pulse with the rising edge of the FREQ signal. The square wave input
signal with duty cycle 0.2 to 0.8 is allowed. Variation of the duty cycle does not affect laser
characteristic.
For the input frequency and internal laser pulse is asynchronous, the delay from the
rising edge of the FREQ signal to laser output ranges from 0 to base period.
