Integrated Diode Side-pumped
Solid-State Lasers (DPSS Lasers) |
|
 Conventional
solid-state lasers are pumped by a flashlamp. The lifetime of the lamp
is generally shorter than 400 hours and the coupling efficiency of the
lamp power into the laser crystal is very low (normally less than 3%),
resulting in various undesirable effects such as serious thermal
lensing, bad beam quality, bulky physical size and frequent replacement
of the flashlamps. Solid-state lasers have undergone a renaissance since
the development of reliable and cheap diode lasers, which can be used as
pump sources. It has led to a new class of diode-pumped solid-state
(DPSS) lasers which have been demonstrated to be highly efficient,
reliable, and are attractive for a wide range of applications. DPSS
lasers take the advantages of both flashlamp-pumped solid-state lasers
and diode lasers, and therefore exhibit more advantages as follows:
-
High
optical-to-optical conversion efficiency (>50%);
-
Good
laser beam quality (M2 ~1.1);
-
Stable
output laser power (�1%);
-
Low
maintenance or maintenance-free;
-
Compact
in size.
The
performance of our DPSS lasers is comparable with similar products in
the world, but their prices are very attractive and competitive. These
lasers are widely used in industries such as electronics, semiconductor,
hardware, precision machining, science, defense and medicine for laser
marking, trimming and cutting.

OEM Diode Side-pumped Solid-State Lasers |
|
For OEM
users or laser integrators, we can provide OEM and system integrators
with a range of high performance components and sub-assemblies of
diode-pumped Nd:YAG laser at more attractive prices. These components
and sub-assemblies include laser
head (diode pump module, laser resonator, Q-switch cell), diode
driver and chiller. The options are beam expander, aperture, Q-switch.
1. Laser Head
A basic laser head consists of
laser base (optical rail),
diode module,
output
coupler with mount, rear mirror with mount,
front plate, rear plate, and cover. The options may include
beam expander with
mount,
AO Q-switch cell with mount,
aperture with mount
and control cabinet.
