Femtosecond laser’s average power output exceeds 20 W
The IMPULSE® is an all-diode, direct diode-pumped, Yb-doped fiber oscillator/amplifier. Available from Clark-MXR Inc., this high-average-power femtosecond laser features all-solid-state construction with a user-adjustable rep rate from single shot to 25 MHz, greater than 20-W average power output, and sub-250 femtosecond pulse duration.
Suitable for micromachining, the system can produce variable pulse energies up to 10 μJ. The design combines the low noise of solid-state operation with high spatial mode quality of fiber lasers. All major parameters are computer-controlled, and the unit is iPhone®/iPod2® App-enabled.
