Benefits: - Any desired intra-burst PRR can be achieved independently from the initial PRR of the master oscillator - Identical pulse separation inside the GHz bursts is maintained - Short- and long-burst formation modes can be provided. – A short burst is up to about 10 ns burst width (from 2 to tens of pulses in the GHz burst). – A long burst is from ~20 ns up to a few hundred ns in burst width (from tens to thousands of pulses in the GHz burst) - MHz+GHz burst mode - An adjustable amplitude envelope of the GHz bursts is provided - No pre/post pulses in GHz burst. Pure GHz bursts - Ultrashort pulse duration is maintained inside the bursts Patented Method: The Femtolux laser can operate in single-pulse mode, MHz burst mode, GHz burst mode, and MHz + GHz burst mode. A versatile patented method for generating ultra-high-repetition-rate bursts of ultrashort laser pulses is based on an all-in-fiber Active Fiber Loop (AFL) technology. It overcomes many limitations encountered by other fiber- and/or solid-state-based techniques. Technology is protected by international patents and patent applications: WO2021059003, US12438325B2, CN114830462B, KR102707843B1, EP4035234A1.

They are indications of typical performance and will vary with each unit we manufacture. All parameters are specified for a shortest pulse duration. Custom intra-pulse PRR is available upon a request. Depends on the intra-pulse PRR. For more information, please inquire sales@ekspla.com.
PT501 series Mid-Infrared Single Housing Tunable Picosecond Laser System PT501 covers 2300 to 16000 nm at 100 Hz repetition rate, with linewidth under 3 cm⁻¹ across the entire tuning range. The pump laser and OPO share a single compact housing. Mounting the components on the same frame provides a robust solution. It makes laser installation shorter, improves long-term stability, and reduces maintenance costs. Features - Tuning range 2300– 16000 nm (4345– 625 cm‑1) - Hands-free tuning: motorized for the entire tuning range - Linewidth <3 cm‑1 in the entire tuning range - Repetition rate 100 Hz - Air cooled – external water supply is not required - Beam direction stability in the entire tuning range - Single housing: integrates a pump laser and OPO in a single housing - PC control via USB (virtual COM port), RS232, LAN using REST API commands - Fast wavelength scan (sweep) Applications - Infrared spectroscopy - SFG (sum frequency generation spectroscopy) Description PT501 integrates the pump laser and OPO in one housing, covering 2300 to 16000 nm at 100 Hz. A shared frame removes the inter-unit alignment interface that separate-box MIR systems require. That interface is the main origin of long-term pointing drift. The system is air-cooled; no external water supply is needed. Wavelength tuning is fully automatic. Closed-loop micro-stepping motors drive the tuning elements, and thermo-controllers maintain the nonlinear crystal temperatures. The sweep from 2300 to 16000 nm runs without manual adjustment, including the transition between OPO and DFG output stages. For customer convenience, the laser can be operated from a master device or a personal computer using various interfaces. Depending on the system configuration, control is available via the USB interface (REST API over RNDIS or VCP with ASCII commands), the RS-232 interface (ASCII commands), the LAN interface (REST API), or from the remote control pad with a backlit display that remains easy to read even while wearing laser safety glasses. Communication interface - USB : REST API over RNDIS - RS232: ASCII commands - LAN: REST API - Remote control pad: With a backlit display Default. Other option– ASCII commands over virtual serial port. Available models - PT501: Provides a narrowband radiation with a linewidth <3 cm‑1 in the entire tuning range: 2300– 16000 nm (4345– 625 cm‑1).
