User Manual
Introduction
JetLasers’ PL-E Pro series feature AC integration, robust design, flexible
design, focus/defocus mechanism, added safety features, metal button,
spare barrel, long runtime and and high reliability make them a better
option for outdoor or field use where a a high power, high stability
handheld laser is required. The PL-E Pro series lasers are good for lab
use where portability and low cost are necessary.
What makes PL-E Pro different from previous versions?
1. The build quality strengthened, the intuitiveness enhanced in design!
2. Modular battery barrel, assembling + shipping friendly, PL-E
convertible!
3. Tail safety pin added, more input sources explored, user safety
fortified!
4. Simplifying the functions and minimizing the failure rate!

5. Aperture cap: anti-dust, user safety considered!

Safety
•NEVER aim a laser at people, animals, or aircrafts.!
•NEVER look directly into the beam of a laser.!
•ALWAYS use protective eyewear when using laser.!
◦Be certain to use eyeglasses designs for the wavelength of the
laser, e.g., don’t use safety glasses designed with blue lasers
with red lasers; the red wavelengths will not be filtered by the
eyeglass.!
•ALWAYS use caution when using high powered lasers indoors.!

•BEWARE of laser beam reflections off of mirrors or other reflective
surfaces!
Batteries
•PL-E Pro series is by default a 26650 host at 28cm in length.
18650/16340 lithium-ion batteries may also be used with the
included case reducers. Some lithium-ion batteries have flat-tops (as
opposed to batteries with a “button-top”). Flat-top batteries must use
the included button magnets to make contact with the second
battery.!
◦Attach the small magnets to the positive end of the flat-top
batteries.!
•PL-E Pro series at 473/532/635/650/808/980/1064nm takes a single
18650/26650 (3.7v, fully chargeable to 4.2V) or 5V AC wall adapter.!
•PL-E Pro series at 405/445/465/520nm takes two
16340/18650/26650s (each 3.7v, fully chargeable to 4.2V) or 8V AC
wall adapter.!
◦With two batteries at full charge, the voltage will be at 8.4v and
will not damage the laser diode. !
•The extension tube is included for users to use two 18650/26650
batteries.!
◦With the extension, the laser totals at a length of 35cm.!

• AC wall adapters are not included in the packing list. If you have the
right AC adapter, you can run the laser on AC without the batts
needed.!
Operation
"

PL-E Pro Mechanical Switch
1. Load Batteries
•Load "-" negative end of battery first into the host!
•Reattach the tail switch.!
2. Switch on the Tail Switch
There are two options of tail switches:
•The Keylock Switch: Turn into the keylock on tailcap with the key
Clockwise, the LED indicator will turn on.!
•Simple Button Switch: Depress the button on the tailcap, the LED
indicator for the!
power supply will turn on.
3: Turn the Beam On
•Constantly On/Off Button (the lower button)!
◦Depress Constantly On/Off Button, and the beam will turn on.!
◦Depress it again, and the beam will turn off.!
•Momentarily On/Off Button (the upper button)!
◦Depress the Momentarily On/Off Button, and the beam will turn
on.!
◦Letting go of the button will turn the beam off.!
4..Switch the Beam Off
•Press the Constantly on/off button to turn the beam off.!

•The user can force switch off the laser at any state by using the tail
switch.!
PL-E Pro Series Code Switch
1. Load Batteries
•Load "-" negative end of battery first into the host!
•Reattach the tail switch.!
2. Power Select Button
•Depress the Power Select Button will turn the beam on.!
•By default, the power level will begin at 50% of the max output.!
•Pressing the button a second time will activate 100% of the max
output. !
◦Another single press will cycle between 50% and 100% of the
max output.!
3. Pulse Mode Button
•Depressing Pulse Mode Button will shift Continuous Wave to Pulse
Mode.!
•Depressing either Power Level Button or Pulse Mode Button would
turn Pulse!
mode to Continuous Wave mode.
◦Another single press on Pulse Mode Button will cycle between
Continuous Wave and Pulse Mode.!
4. Standby Mode

•Long Hold (3 seconds) the Power Select Button shifts laser into
Standby Mode.!

5. Switch the Laser Off
•In Standby Mode, depress/keylock the Tail Switch to switch off.!
•The user can force switch off the laser at any state by using the tail
switch.!
Focusing Mechanism
Before we can talk about how the focusing mechanism works, there is one
term that you should be familiar with - beam divergence. Beam
divergence is a measure of how wide a laser beam will expand from its
point of focus.
Contrary to popular belief that a laser will stay as a “dot” as it reaches
miles and miles in distance. All laser beams will diverge, i.e., the “dot” will
become big as it reaches further distance. By using a lense or a set of
lenses, we can control the divergence at a certain distance.
Understanding this concept will help you understand how a laser “burns.”
Inside the laser units, there are a set of lense that by turning the focusing
ring, you can achieve the following beam configurations. When you are
turning the focusing ring, you are essentially moving the lense to change
the focal length of the lense and the laser diode.

•Figure A is known as a “diverging beam.” In this configuration, the
beam begins as a narrow-gathered beam and eventually expands
as the distance increases.!
•Figure B is known as a “converging beam.” In this configuration, the
beam begins as a wide beam, but at certain distance will converge,
i.e., come together, and then it will diverge again.!
•Figure C is known as a “collimated beam.” In this configuration, the
beam begins as a wide beam and remains so throughout the length
of the beam. (remember that every laser beam will begin to diverge,
i.e., becoming wider, at some point (unless there are more lenses to
refocus the beam). !
A laser, like all light source, is taking that light source and focusing it to a
point to increase the intensity of that light. The idea is very similar to
taking a magnifying glass to focus sunlight to burn something.
On the topic of burning, a laser once again is a light source. Light in and
of itself cannot burn. However, taking that same light and gathering it into

a very narrow beam will begin ignition, if there is enough intensity (the
higher wattage equates to higher intensity).
The target must also be taken into account. Light (not dark) objects will
reflect a light source instead of absorbing it. On the other hand, a dark
object will be able to absorb light better. Remember, the more light energy
an object absorbs, the more easily it will ignite something.
One last thing to note, focusing your laser according to figure B will be the
best for burning things. However, take note that the point of convergence
will also shift depending on your focus settings.
AC Adapter
•How to Run the laser on AC adapter: !
AC adapter is also called power adapter, because it converts AC
power from a wall jack into DC power for the laser module. PL-E
Pro lasers can run on AC adapter either with or without batteries
loaded. To use it, plug the AC cord into a wall socket, and then
connect the DC end of the adapter to the DC jack on the PL-E Pro
laser. The LED indicator will light up.
ALWAYS USE PRECAUTION WHEN USING HIGH POWERED
LASERS!
