Femtosecond fiber laser Model Pearl-70P300 - request a quote
Femtosecond pulsed lasers are used in many fields of physics, biology, medicine and many other natural sciences and applications: material processing, multiphoton microscopy, «pump-probe» spectroscopy, parametric generation and optical frequency metrology. Femtosecond fiber lasers offer stable and steady operation without constant realignment.
The Pearl-70P300 laser comprises: a passively mode-locked fiber laser, providing pulses with repetition rate 60 MHz and having duration of 250-5000 fs, an amplifier based on Er3+ doped fiber waveguide with pumping by two laser diodes, a prism compressor for amplified pulse compression.
Pearl Ultra-Compact Ultrafast Picosecond Fiber Oscillator
Reef femtosecond autocorrelators
The autocorrelation technique is the most common method used to determine laser pulse width characteristics on a femtosecond time scale.
The basic optical configuration of the autocorrelator is similar to that of an interferometer (Figure.1). An incoming pulse train is split into two beams of equal intensity. An adjustable optical delay is inserted into one of the arms. The two beams are then recombined within a nonlinear material (semiconductor) for two photon absorption (TPA). The incident pulses directly generate a nonlinear TPA photocurrent in the semiconductor, and the detection of this photocurrent as a function of interferometer optical delay between the interacting pulses yields the pulse autocorrelation function. The TPA process is polarization-independent and non-phasematched, simplifying alignment.
Reef-RT autocorrelator measures laser pulse durations ranging from 20 femtoseconds to picosecond regime. It measures pulse widths from both low energy, high repetition rate oscillators and high energy, low repetition rate amplifiers. Compact control unit operates autocorrelator head and optional spectrometer through on-screen menus. Autocorrelation trace and spectrum can be displayed and analyzed on screen or downloaded to remote computer.

Trestles Fourth Harmonic Generator - request a quote
Trestles FHG is designed to work with Ti:sapphire lasers, such as the Trestles Ti:sapphire laser to provide fourth harmonic generation. Trestles FHG is an affordable and easy solution to generating pulses around 200 nm.
Trestles FHG is available in two versions. The first version uses the third harmonic mixed with the fundamental wavelength to produce fourth harmonic generation. This option provides the fundamental, as well as the second, third and fourth harmonics. For input of 810 nm, 1 W, 82MHz and 50 fs, output of the fourth harmonic is at 203 nm, 300-400 fs and power is 3 mW. The second option uses two separate second harmonic generation stages to produce fourth harmonic generation. With input of 810 nm, 1 W, 82 MHz and 50 fs, output of the fourth harmonic is at 210 nm, pulse width of 500 fs and power of 10 mW.
The Trestles FHG from Del Mar Photonics is an easily installed solution for adding functionality to any femtosecond laser system. Extended ranges will increase capabilities for research, and specific applications such as microscopy and spectroscopy.
