Cavityless™ Tunable Picosecond Pulse Source
Ultra-low-noise, 40-GHz laser pulses with seamless ultrawide wavelength tuning
The Cavityless™ Series tunable picosecond pulse source is the first ultrafast fiber laser which provides ultra-low-jitter pulses without relying on mode-locking and its inherent instabilities. The new technology provides programmable-rate, pulsed laser output with true continuous λ-tuning uninhibited by the traditional use of optical cavities.
Seamless ultrawide tunability
Free from the typical constraints inherent to cavity-based mode-locked lasers, the Cavityless Series is the first laser source to combine seamless wavelength tunability and continuously programmable repetition rate that simply cannot be matched by conventional mode-locked technology. The Cavityless Series is the first laser to simultaneously provide:
- True continuous (mode-hop-free) C+L wavelength tunability
- Short pulses (< 2.5ps)
- High, programmable repetition rate (up to 56 GHz)
- High power (200 mW)
- “Instant-on” turn-key operation without cavity stabilization or locking
Excellent pulse shape with high extinction ratio
