Lastek's Yabby is an all-solid-state optical pulse compressor that can reduce the pulse duration from common femtosecond Ytterbium lasers operating around 1030nm by factors of up to 6 with high efficiency. Yabby is optimised for pulse energies in the tens of microjoule range and uses a novel multi-pass cell containing a nonlinear element to chirp the input pulse so that it can then be compressed using dispersion- compensating mirrors. By employing high efficiency reflective or anti- reflective coatings on all optical components the overall transmission of the system is >90% with typically >90% of that energy contained in the compressed pulse.
• Typically 325fs to 65fs, 5X compression ratio!
• Unique patented multi-pass cell design.
At-a-glance:
Yabby is designed to compress pulses from industrial Yb fiber lasers producing 275 - 400fs pulses around 1030nm.
Features:
• Compression ratio CR typically 5-6
• Designed specifically for pulses containing 10’s µJ of energy
• The Kerr nonlinearity of a glass plate contained in a novel multi-pass cell is used to chirp the input pulses
• Separate chirped mirrors compress the pulse from the cell to near the time-bandwidth limit
• No compressed gas required
Benefits
• High transmission efficiency >90%
• Typically, >90% of energy is contained in compressed pulse
• Multiple configurations possible to allow for different input pulse energy
• Compact, maintenance free design
• Maintains pointing stability of the input laser
• Beam quality of the output beam is close to that of the input laser
Applications:
• Pump-probe studies
