808nm wavelength Single Emitter Diode Laser for Pumping and Medical
Application
Packaged single emitter diode laser is a semiconductor device
similar to a light-emitting diode in which the laser beam is
created at the diode's junction. Driven by voltage, laser diodes
can directly convert electrical energy into light. With three
package design options, LDM-0808-003W-*3 is easy to mount and
provides good thermal contact, making it an ideal choice for high
power and OEM applications.
LDM-0808-003W-*3 is one type of HTOE LDM series packaged single
emitters, which are Fabry-Perot cavity semiconductor lasers based
on Quantum-well epitaxy and ridge waveguide structure design.
Standard options are 635nm, 650nm, 670nm, 785nm, 808nm, 830nm,
915nm, 940nm, 980nm and 1064 nm center wavelength single emitters
packaged on TO mounts, CoS mounts, C-mounts and F-mounts. HTOE
packaged single emitter diodes provide superior reliability and
performance by providing beam shaping services like fast-axis
compression according to customer demands.

Notice
- Item model notice: LDM (Item model), 0808 (Center wavelength), 003W
(Output power), *3 (Heat sink structure and item width).
- Data in the sheet are all based on C-mount package heat sink
testing.
ESD precautions must be taken when handling unit.
A dry environment should be provided when storing or operating a
device with an open diode laser facet at temperatures below the
ambient dew point. Failure to do so will cause condensation on the
unit and can destroy it.

ESD Cautions
The primary cause of diode failure is unexpected electrostatic
discharge. To help prevent device failures, be sure to handle
devices with extreme care. Users should always wear an ESD wrist
strap, ground all applicable work surfaces and follow anti-static
techniques when handling diode lasers.
