CHAPTER 3: PROGRAMMING FUNCTIONS
LW500A/LW600A PULSED Nd:YAG LASER
990-539 3-7
2. REFERENCE VALUE: – Displays the estimated laser output energy in Joules (J) of the programmed
waveform. Though the Laser computes the output energy based on the programmed settings, due to
optical and electrical characteristics, its estimated value will differ slightly from the monitored
(measured) value. Use the estimated laser output energy as an approximation.
3. SHOT:
– Sets the number of times (shots) you want to output the laser beam consecutively. The
setting can be changed between 0 and 9999. When REPEAT > 0 and SHOT = 0, the Laser will continue
to output a laser beam until it receives a laser-stop signal.
4. REPEAT:
– Sets the number of laser pulses per second (PPS). The setting can be changed between 0
and 500. When set to 0, the laser pulse is not repeated.
5. COOL
– Field used to set the cooling time between FLASH1 – FLASH2 and FLASH2 – FLASH3 when
there will be no laser output. When set to 0, there will be no cooling period.
6. SEAM:
– Field used to activate the Seam Weld function that is used to suppress the beginning and
ending of the output waveform over a predetermined amount of pulses (Fade-In / Fade-Out).
ON
turns the Seam Weld function ON. Likewise, OFF turns the Seam Weld function OFF.
Note: REPEAT and SHOT must be > 1.
7. FORM: FIX Settings
– The FORM: FIX settings are used to define the pulse shape of the Laser output
over three time segments. The pulse shape is defined using the SLOPE, FLASH1, FLASH2, FLASH3,
SLOPE
and the COOLing parameters. FLASH 1 / 2/ 3 are used to define how long (mS) and how much
power (%) should be delivered to the output during that particular time segment.
SLOPE Sets the upslope (the laser beam is gradually intensified) within the time set for
FLASH1. Set FLASH1 first, and then set SLOPE (Note: SLOPE ≤ FLASH1).
SLOPE can also eliminate “overshoot” on the rising edge of the output pulse.
FLASH1
Sets the first segment laser output time and the first laser output value (%).
FLASH2
Sets the second segment laser output time and the second laser output value (%).
FLASH3
Sets the third segment laser output time and the third laser output value (%).
SLOPE Sets the downslope (the laser beam gradually weakens) within the time set for
FLASH 3. (Note: SLOPE ≤ FLASH3)
The
FORM: FIX setting limits are defined as follows:
Laser Model
 SLOPE + FLASH1 + COOL1 + FLASH2 + COOL2 + FLASH3 +  SLOPE
LW500A(E) / ML-2651B(-CE) 0.1 ≤ t ≤ 99.9 ms and 0 – 200% value (8.0kW maximum)
LW600A(E) / ML-2650B(-CE) 0.1 ≤ t ≤ 99.9 ms and 0 – 200% value (10.0kW maximum)
