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.
