Menlo Systems YLMO-Seed Femtosecond Ytterbium Laser

YLMO-Seed Femtosecond Ytterbium Laser

Menlo Systems’ Ytterbium based femtosecond fiber laser oscillator integrates the latest developments in fiber technology and incorporates these enhancements into an easy-to-use product.

Their patented figure 9® technology delivers reliable and consistent mode-locking, which is ideally suited to ensure long-term stable operation. The PM-fiber design guarantees excellent stability and low noise, even in harsh environments with high fluctuations in temperature. As a seed source for amplifiers, the YLMO-Seed offers easy integration and maintenance-free operation, engineered for 24/7 operation.

Central Wavelength factory set between 1030 nm and 1064 nm, ± 1 nm
Average Power >200 mW (@50 MHz)
Pulse Energy >4 nJ
Bandwidth>15 nm (narrower bandwidth on request)  
Pulse Width (FWHM)chirped, supporting <150 fs
Repetition Ratefactory set between 30 MHz and 100 MHz, ± 1 MHz
Output PortSC/APC fiber mating sleeve
Polarizationlinear, PM fiber (PER: typ >20 dB)
Pulse Picking Option (only for 50 MHz or lower)Realized by integrated fast AOM: Mode 1: Divides repetition rate by factor 3 or higher, pulse energy stays constant. Mode 2: Can be used as fast amplitude modulator.
