Ti-100P Pulsed Laser Addendum
Overview
The ti100P is a pulsed laser and differs from the standard continuous wave ti Series lasers. While the
output power characteristics and specifications are different, the installation, integration, and operating
information is unchanged.
The ti100p is shipped with a beam expander mounted and aligned to the faceplate. Available expansion
ratios are 3X, 4X, and 5X. Beam diameter (1/e2) at the beam expander output is shown in the table
below
:
Table 4-15 ti Series Beam Expanders
Expander Ratio Beam Diameter Beam Divergence
3X 6.6 mm ~2.3 mrad
4X 8.8 mm ~1.8 mrad
5X 11.0 mm ~1.4 mrad
Important Note: Do not apply a tickle signal. Do not use a UC-2000 Controller or other PWM
signal source that generates a tickle signal. Applying a tickle signal to the ti100p may interfere with
its pulsing performance
.
Caution: Possible Equipment Damage
Shut down the laser and carefully inspect each optic in the beam delivery path, including the laser’s output coupler.
Remember that optics are fragile and must be handled carefully, preferably by the mounting ring only. If the optic requires
cleaning, then refer to Maintenance for cleaning instructions. Use only recommended cleaning materials (see Required
Cleaning Materials table) to prevent scratching delicate optical surfaces.
If the focusing optic is pitted, it must be replaced immediately. Because of the extremely high-power density of ti Series
lasers, pits or debris on the lens surface may absorb enough energy from the focused beam to crack the lens. If this
happens, other optics in the beam path may be contaminated or damaged as well.
A risk of exposure to toxic elements, like zinc selenide, may result when certain optical or beam delivery components are damaged.
In the event of damage to laser, marking head, or beam delivery optics, contact SYNRAD, Inc. or the optics manufacturer for handling
instructions
