eMOPA532-200

Our MOPA (Master Oscillator Power Amplifier) product line is generally based on a diode-pumped, passively Q-switched solid-state laser as the master oscillator and a diode-pumped power amplifier with a special optical design. Both work on the basis of a Nd:YAG crystal and the 1064 nm fundamental wave. After amplification, the latter is converted into frequency multiples by frequency conversion with non-linear optics. The main oscillator and frequency conversion module are inside an air-sealed aluminum housing, allowing them to operate in relatively rough environments without contamination or loss of reliability. Wavelengths from the DUV to the IR spectral range can be generated:

• 213 nm
• 266 nm
• 355 nm
• 532 nm
• Unconverted wavelength 1064 nm

The MOPA laser system is available as a stand-alone version or as an OEM (Original Equipment Manufacturer) version. Additional options such as a synchronization module or an electrical beam blocker can be ordered separately and are available depending on the laser wavelength.

The MOPA series includes three product lines:

• MOPAs with high peak power
• MOPAs with high average power
• eMOPAs (eco-MOPAs)

The latter are the latest development in this series. The “e” here stands for “eco”. The reason for this is the efficiency of the eMOPA, in which – unlike its predecessors – the amplifier stage and the associated pump laser are completely built into the laser head. As a result, the control system of the eMOPA is much more compact, which saves acquisition costs. The eMOPA is ideal for 24/7 industrial use and is primarily used in ophthalmology. The laser is usually limited to a repetition rate of 1 kHz, where its performance is optimized. By adapting the lasers to the requirements of our customers, a wide range of applications is possible:

• Ablation
• Photoacoustic
• LIBS
• Marking
• Any many more

Due to the special technical design of the laser system, it operates in transversal single mode with high peak-to-peak pulse power stability, good average power stability and short pulse duration. The compact design of the laser allows the laser head and the control unit to be integrated into existing systems with little effort.

The MOPA laser consists of a passively Q-switched pulsed microchip laser operating in single pulse mode at different repetition rates – depending on the MOPA model. It can either have an external trigger source or an internal trigger source using special software commands. The pulse energy can be set via simple terminal or software commands. The laser system is suitable for laser marking and processing as well as for applications in analytical metrology.
