Y-LASER Successfully Delivered Yb+MPC Femtosecond Laser System
In the field of ultrafast laser systems, Ti:sapphire femtosecond lasers have long been regarded as the standard solution for achieving millijoule-level energy and sub-40 fs pulse widths. However, with the continuous advancement of laser technology, an increasing number of novel solutions have emerged, offering performance comparable to—and in some aspects even surpassing—traditional Ti:sapphire systems. Among these, the configuration of Yb-doped femtosecond lasers combined with multi-pass cavity pulse compressors (MPC) is becoming a more efficient, cost-effective, and compact alternative.
Based on this advantage, a research institute in Nanjing ultimately selected Y-LASER to provide a high-power, high-energy, ultrashort-pulse laser system for studies related to high-order harmonic generation and aerodynamics. The system has been successfully delivered and is performing well.
Why Yb + MPC is Becoming a Breakthrough Choice?
The Yb+MPC system offers significant advantages such as a compact structure, high average power, and strong system integration, making it an ideal alternative to Ti:sapphire femtosecond laser systems.
1.Compact Structure and High Average Power
Compared to Ti:sapphire systems, Yb femtosecond lasers feature a more compact structure. Not only are the lasers smaller in size, but they also deliver higher average power output within the same power range, offering significant advantages in terms of space utilization and integration. This is particularly critical for our laboratory—achieving efficient laser output and system integration within limited space was a key factor in our decision to choose the Yb laser.
2.High System Integration
Compared to traditional Ti:sapphire femtosecond systems, Yb femtosecond laser systems offer higher system integration. Their design reduces reliance on the large optical pumping equipment and water cooling systems required by conventional Ti:sapphire lasers, making the overall system not only more efficient but also easier to maintain. When combined with a high-performance multi-pass cavity (MPC) pulse compressor, the Yb femtosecond laser achieves excellent pulse compression within an extremely compact volume, meeting the demands of various cutting-edge scientific research and industrial applications.
3.Performance Enhancement with MPC Pulse Compressor
The combination of the multi-pass cavity pulse compressor (MPC) with the Yb laser system enhances the overall pulse compression performance. In practical applications, by using the 2mJ high-energy femtosecond solid-state laser together with the MPC pulse compressor, we achieved a pulse width of less than 40 fs with excellent output beam quality, ensuring the system's stability and reliability in high-precision applications.
4.Stability and Consistency
When selecting a femtosecond laser system, stability and consistency are among the core factors we consider. Using the provided 2mJ high-energy femtosecond solid-state laser, we experienced excellent long-term stability and consistency. After prolonged operation, the system maintained stable output, with all performance indicators—such as pulse energy, pulse width, and beam quality—remaining within expected ranges. The integration of the MPC pulse compressor further ensured the system's stability and efficient output under varying operating conditions.
