Among various technological applications, high-power pulsed lasers are important light sources. In high-power pulsed laser systems, the seed laser is the key factor determining the performance of the entire system, and the mode purity of the seed light determines the output quality of the laser system. The seed laser generates initial light pulses with low noise, narrow linewidth, and high stability in the resonator cavity, providing a reference signal for the subsequent amplification chain. RealLight, in response to the demand for precision equipment such as medical aesthetics, has launched the MCD series low-repetition-rate OEM microchip lasers. With a passive Q-switched microchip configuration and strict parameter control, it has become the preferred seed source for high-end laser equipment.

 

The core principle of the seed laser is to inject the pure, stable and parameter-controllable initial optical signal output by the seed laser into the master oscillator power amplifier (MOPA) chain. Through pump amplification, the energy is enhanced, achieving a significant increase in energy. At the same time, the beam quality, pulse shape and inherent spectral characteristics of the seed laser are completely retained. Compared with directly generating high-power pulses, this seed amplification scheme can significantly reduce phase noise, suppress mode hopping, and produce a laser with narrower pulse width, higher peak power and better beam quality.

Low Repetition Rate OEM Microchip Laser, Seed Source Parameters

The MCD series low-repetition-rate microchip laser adopts diode pumping and passive Q-switching technology. It integrates an Nd:YAG gain crystal and a Cr⁴⁺:YAG saturable absorber, and achieves sub-nanosecond pulse output with a short-cavity microchip structure. The central wavelength is 1064nm, with a single pulse width of 350ps. The repetition frequency is 10Hz, with the single pulse energy reaching up to 500μJ and the peak power up to kW level. The output is in the TEM00 mode, providing sufficient initial energy and pure pulse waveform for subsequent amplification. This product features an integrated fully-sealed laser head, along with a miniaturized driving circuit. It has a compact structure and can also be equipped with an optical isolator made by RealLight, suitable for equipment integration and complex working conditions.

High-quality seeds can ensure the output accuracy and safety of medical aesthetic laser equipment. The MCD series features narrow pulse width, high stability and excellent beam quality, enabling it to provide high-quality initial light sources for various medical aesthetic devices. After appropriate amplification, it can achieve precise energy and waveform output, thereby providing a strong guarantee for its excellent therapeutic effect and safe operation.

Thanks to the meticulous design of parameters and the rigorous engineering implementation of the product, RealLight has successfully developed high-performance and highly adaptable OEM seed light source products with deep technical expertise and strict quality control over the product. These products provide stable, precise and reliable pre-light signals for medical aesthetics and high-end laser equipment.
