PHAROS is a series of femtosecond lasers combining millijoule pulse energy and high average power. PHAROS features a mechanical and optical design optimized for both scientific and industrial applications. A compact, thermally-stabilized, and sealed design enables PHAROS integration into various optical setups and machining workstations. Diode-pumped Yb medium significantly reduces maintenance costs and provides a long laser lifetime, while the robust optomechanical design enables stable operation in varying environments.

The tunability of PHAROS allows the system to cover applications normally requiring multiple different laser systems. Tunable parameters include pulse duration (100 fs – 20 ps), repetition rate (single-shot – 1 MHz), pulse energy (up to 3 mJ), and average power (up to 20 W). A pulse-on-demand mode is available using the built-in pulse picker. The versatility of PHAROS can be extended by a variety of options, including carrier-envelope phase (CEP) stabilization, repetition rate locking to an external source, and automated harmonic modules.

BiBurst 

Tunable GHz and MHz burst with burst-in-burst capability

Pharos and Carbide-CB3 lasers have an option for tunable GHz and MHz burst with burst-in-burst capability – called BiBurst.

In standard mode, a single pulse is emitted at some fixed frequency. In burst mode, the output consists of pulse packets instead of single pulses. Each packet consists of a certain number of equally separated pulses. MHz-Burst contains N pulses with a nanosecond period, GHz-Burst contains P pulses with a picosecond period. If both bursts are used, the equally separated pulse packets contain sub-packets of pulses
(burst-in-burst, BiBurst).

PHAROS and CARBIDE lasers with the BiBurst option bring new capabilities to high-tech manufacturing industries such as consumer electronics, integrated photonic chip manufacturing, future display manufacturing, and quantum technologies.

 

BiBurst material fabrication areas cover:

  • brittle material drilling and cutting
  • deep engraving
  • selective ablation
  • transparent materials volume modification
  • hidden marking
  • surface functional structuring.

Pharos lasers equipped with automated harmonic generators (HGs) provide a selection of fundamental (1030 nm), second (515 nm), third (343 nm), fourth (257 nm), or fifth (206 nm) harmonic outputs using software control. HGs are perfect for industrial applications that require a single-wavelength output. Modules, mounted directly at the output of the laser, are fully integrated into the system.

Optical Parametric Amplifier I-OPA

The industrial-grade optical parametric amplifier I-OPA series marks a new era of simplicity in the world of tunable wavelength femtosecond light sources. Based on over 10 years of experience producing the ORPHEUS series of optical parametric amplifiers, this solution brings together the tunability of wavelength with the robust industrial-grade design. The I-OPA is a rugged module attachable to PHAROS lasers, providing long-term stability comparable to that of the industrial-grade harmonic generators.

For more information, please visit our product page Integrated Optical Parametric Amplifier I-OPA

 

 

CEP Stablilization

PHAROS lasers can be equipped with feedback electronics for carrier-envelope phase (CEP) stabilization of the output pulses. The carrier-envelope offset (CEO) of the PHAROS oscillator is actively locked to 1/4th of the repetition rate with a < 100 mrad standard deviation. The CEP stable pulses from the synchronized amplifier have a < 350 mrad standard deviation. The CEP drift occurring inside the amplifier and the user’s setup can be compensated with an out of loop f-2f interferometer, which is a part of the complete PHAROS active CEP stabilization package.

 

 

Repetition Rate Stabilization

The oscillator of PHAROS laser can be customized for repetition rate locking applications. Coupled with the necessary feedback electronics, the repetition rate is synchronized to an external RF source using the two piezo stages installed inside the cavity. The repetition rate locking system can assure an integrated timing jitter of less than 200 fs for RF reference frequencies larger than 500 MHz. Continuous phase shifting is available on request.

Hiro 

Stand-alone Harmonics Generator Hiro

HIRO is a free-standing harmonic generator for PHAROS and CARBIDE lasers, as well as FLINT oscillators. It provides a high-efficiency second, third, fourth, and fifth harmonic generation at 515, 343, 258, and 206 nm, respectively. The selection of an active harmonic is manual but requires less than a few seconds, thanks to its unique optomechanical design.

The HIRO harmonic generator for PHAROS and CARBIDE comes in three models: standard, high-power (HP), and high-energy (HE), to perfectly fit the pump laser. The standard HIRO accepts up to 20 W and 1 mJ pump, the high‑power model (HIRO‑HP) takes up to 80 W, and the high‑energy model (HIRO-HE) goes up to 80 W and 3 mJ pump while maintaining the high conversion efficiency and beam quality. Also, HIRO-HP and HIRO-HE are optimized for high stability and temperature control, while the standard HIRO is customizable with additional options such as beam size control, collimation, and white-light continuum generation. All models use beam division and harmonics splitting to enable simultaneous or switchable outputs.

Coupled with FLINT, the HIRO harmonic generator provides second, third or fourth harmonic at a high repetition rate.
