Diode Pumped Solid State (DPSS) Lasers - solid-state lasers, in which the optical pumping is provided by semiconductor diode laser. DPSS lasers are characterized by high efficiency and compactness compared with gas and other solid state lasers.
DPSS lasers have become particularly popular as sources of laser light for many applications from industry and science to broad consumer and entertainment devices.
This laser has the optical scheme of pump semiconductor laser, laser active media and nonlinear crystal frequency doubling. At least, the second and third elements of the scheme require a fine thermal stabilization, as their work is strongly dependent on temperature. In addition in the DPSS, powerful semiconductor lasers are used for pumping, therefore heat dissipation and thermal stabilizing are required too. DPSS lasers efficient operation in many applications requires temperature stabilization with the thermoelectric coolers (TECs).
DPSS lasers are available variety of sizes and performances.
The advantage of TECs is that they can stabilize LD temperature below ambient (cooling mode) or heat it up in reverse case. It is simply required to switch the power supply polarity on TEC.
TEC has unique reliability of several hundred thousand hours of continuous operation. It is more than 20-25 years of operation without maintenance and replacement, which is important for telecommunication systems.
RMT produces series TECs for DPSS lasers. These are powerful single-stage modules of all the . RMT recommends 1MC06, 1MD06, 1MD10 and 1MDL06 Series for DPSS applications. Depending on the design (body), you can use a wide variety of standard sizes of thermoelectric modules for such applications.
