With the feature of the cold light source, DPSS laser series is mainly used in flying marking, PCB cutting, FPC cover film cutting, marking on plastic material and on glass material, and 3D printing, etc. The applications of DPSS laser include integrated circuit industry, crafts production industry, resin 3D printing, and marking industry.

DPSS Lasers FAQs

Question: How does a DPSS laser work?

Answer

DPSS laser is a solid-state laser that uses a gain medium that is solid. The gain medium of a DPSS laser consists of a glass or crystalline host material. The most common host materials are neodymium-doped yttrium aluminum garnet (Nd: YAG), ytterbium-doped glasses and neodymium-doped glass (Nd: glass). The gain medium is optically pumped by using laser diodes. The DPSS laser can generate a wide range of wavelengths based on the gain medium material. From the fundamental wavelengths, additional wavelengths can be generated by frequency doubling or second harmonic generation.

Question: What's the full form of DPSS laser?

Answer

Diode-pumped solid-state laser

Question: Does the output power of a DPSS laser depends only on its diode power?

Answer

The output power of the DPSS laser depends not only on the diode power but also on other parameters such as temperature of the laser, crystal gain medium, and optical assembly.

Question: What is the minimum time pulse length for a DPSS laser in order to get no strange transient responses?

Answer

The currently available minimum pulse width of the DPSS laser is about 8-10ns. This pulse width is achieved without effecting the laser operation and without any strange transient responses. If you need any other pulse width, we can customize our laser according to your specifications. Customizing lasers for different application is one of our advantages.

Question: DPSS vs. diode laser advantages?

Answer

DPSS lasers generally have a higher beam quality than diode lasers.

DPSS laser can reach very high powers and at the same time maintaining good beam quality. On the other hand, diode lasers can only reach a few hundred milliwatts unless they operate in multiple transverse modes. Such multi-mode lasers have a larger beam diameter and a greater divergence, which often makes them less desirable for single-mode operation.

In a DPSS laser, the crystal is pumped by the diode acts as its own laser, hence the quality of the output beam is independent of that of the input beam.
