The industry leader in high-power chips.
Lasertel’s Power Series delivers reliable power. These
LT1000-1.5W unmounted chips are ideal for a diverse base of customers. Lasertel’s partnering spirit and
“one-stop shopping” offer end users with in-house mounting and packaging capabilities – a unique
opportunity to define and meet their own customer specifications. At an output power of 1.5 Watts CW,
the LT1000-1.5W chips feature wavelengths from 808 to 915 nm. Typical emitted beam divergence is
34 degrees in the fast axis and 8 degrees in the slow axis (FWHM), making the lasers especially useful for
both commercial and solid-state pumping applications. For large OEM users, the Power Series offers
options for custom-designed heat sink packaging, diode mounting platforms, and special lensing to boost
beam quality. Please contact us at 520-744-5700 or email sales@lasertel.com to discuss your application.

Notes
1 ) TM or TE polarization available, consult your Lasertel representative.
2 ) Optional mask configurations available, consult factory.
3 ) Center wavelength specification applicable when mounted on Lasertel C or CT submounts.
4 ) Specifications subject to change without notice.
Safety
Caution: Laser light emitted
from any diode laser is invisible
and may be harmful to the hu-
man eye. Avoid looking directly
into the diode laser aperture
when the device is in operation.
Note! The use of optical instru-
ments with this product will
increase eye hazard.
ESD Caution
Handle diode lasers with
extreme care to prevent electro-
static discharge, the #1 cause
of unexpected diode failure.
You can prevent ESD by always
wearing wrist straps, grounding
all applicable work surfaces,
and following extremely rigorous
anti-static techniques when
handling diode lasers.
Warranty
All Lasertel products are covered
by a limited warranty to ensure
customer satisfaction. Please
see your Lasertel, Inc. product
purchase agreement for com-
plete details, or check with your
Lasertel sales representative.
Notice
Lasertel continually improves
its products to provide cus-
tomers with the best value,
outstanding quality and reliability,
and broadest range of choices.
