Light Conversion Femtosecond Lasers
Light Conversion is a Lithuanian maker of femtosecond lasers, optical parametric amplifiers, OPCPA systems, spectroscopy systems and microscopy lasers, founded in 1994 in Vilnius, with over 10 000 systems installed.
CARBIDE industrial femtosecond lasers
Hundreds of CARBIDE femtosecond lasers run 24/7 in industrial environments. The water-cooled CB3 delivers up to 120 W and 2 mJ with 250 fs – 10 ps pulses from single-shot to 10 MHz. CB3-UV emits up to 50 W at 343 nm, and the air-cooled CB5 gives up to 6 W and 100 µJ.
- Output power up to 120 W
- Pulse energy up to 2 mJ
- UV output at 343 nm
- Air-cooled model: 6 W
PHAROS high-energy femtosecond lasers
PHAROS delivers up to 5 mJ and up to 20 W, pulse duration from 100 fs to 20 ps and repetition rate from single-shot to 1 MHz. The thermally stabilized sealed design fits optical setups and machining stations. Options: CEP stabilization, repetition rate locking, harmonics and OPAs.
- Pulse energy up to 5 mJ
- Average power up to 20 W
- Pulse duration 100 fs – 20 ps
- Repetition rate up to 1 MHz
FLINT femtosecond oscillators
FLINT oscillators use the industrial-grade design of the CARBIDE and PHAROS series. FLINT-FL2 offers up to 20 W, 0.5 µJ and pulses down to 50 fs at 10, 40 or 80 MHz. FLINT-FL1 supports CEP stabilization or repetition rate locking at 60–90 MHz; an integrated module adds 515 nm output.
- Output power up to 20 W
- Pulse duration from 50 fs
- Repetition rate 10, 40 or 80 MHz
- Second harmonic 515 nm
I-OPA, ORPHEUS and TOPAS optical parametric amplifiers
These OPAs are pumped by CARBIDE or PHAROS lasers. ORPHEUS accepts up to 80 W pump and covers 190–16 000 nm with an extension module. The sealed I-OPA is integrated into the laser and takes up to 40 W and 20–400 µJ. TOPAS-Prime serves Ti:sapphire lasers from 189 nm to 20 µm.
- Tuning range 190–16 000 nm
- Pump power up to 80 W
- Integrated OPA up to 40 W
- Ti:sapphire OPA to 20 µm
OPCPA systems
ORPHEUS-OPCPA delivers few-cycle, CEP-stable pulses at 800, 1050, 1600 or 2000 nm. Synchronized with CARBIDE or PHAROS lasers, it reaches up to 480 W and 20 mJ of pump at 1 kHz – 1 MHz. The OPCPA-HE system provides up to 250 mJ at 10 Hz – 1 kHz.
- Pump power up to 480 W
- Pump energy up to 20 mJ
- CEP stability < 250 mrad
- Pulse energy up to 250 mJ
HARPIA spectrometers and CRONUS lasers
The HARPIA-TA transient absorption spectrometer probes 350–1100 nm, 350–1600 nm or 2000–13 000 nm, with fluorescence modules. HARPIA-Light is a Class 1 tabletop system with a CARBIDE laser and 7.5 ns delay line. CRONUS-2P (700–1100 nm) and CRONUS-3P (1250–1800 nm) serve microscopy.
- Probe range 350–1600 nm
- Mid-IR probe to 13 000 nm
- Delay line 7.5 ns
- Microscopy 1250–1800 nm
Selecting a Light Conversion laser system
A femtosecond laser is chosen by power, pulse energy and duration: CARBIDE offers up to 120 W and 2 mJ for industrial processing in air-cooled (CB5) or water-cooled (CB3) models; PHAROS gives up to 5 mJ, 100 fs to 20 ps and up to 1 MHz for scientific setups and machining workstations; FLINT oscillators reach 20 W at 10, 40 or 80 MHz.
For wavelength tuning an OPA is added to the laser: ORPHEUS (190–16 000 nm, up to 80 W pump), the integrated I-OPA or TOPAS-Prime for Ti:sapphire lasers. Few-cycle pulses come from ORPHEUS-OPCPA systems, time-resolved spectroscopy from HARPIA, and multiphoton microscopy from CRONUS lasers.
Light Conversion manufacturing
Light Conversion was founded in 1994 as a spin-off from Vilnius University and is headquartered in Vilnius, Lithuania. Production, clean rooms and R&D laboratories occupy 17 500 m², and over 800 employees work at the company, 15% of them in R&D.
Over 10 000 systems are installed worldwide. Regional offices operate in the US, China and South Korea. In 2026 the company acquired Class 5 Photonics.
