Generating Color Centers with Femtosecond Lasers
Color centers are of high interest in quantum technologies as single-photon sources or spin qubits. Researchers from Australia and Japan have applied PHAROS femtosecond lasers to generate vacancy-related color centers. The work highlights the simplicity and flexibility of laser writing of color center arrays.
This research appears in the article: “Color Centers Enabled by Direct Femto-Second Laser Writing in Wide Bandgap Semiconductors.”

The PHAROS laser from Light Conversion is a femtosecond laser system combining millijoule pulse energies and high average powers. PHAROS features a mechanical and optical design optimized for industrial applications such as precise material processing. Compact size, an integrated thermal stabilization system, and sealed design allow PHAROS integration into machining workstations.
Laser diodes pumping Yb medium significantly reduces maintenance costs and provides a long laser lifetime. Software tunability of PHAROS allows the system to cover applications normally requiring different classes of laser. Tunable parameters include pulse duration (190 fs – 20 ps), repetition rate (single pulse to 1 MHz), pulse energy (up to 2 mJ) and average power (up to 20 W). Its power level is sufficient for most material processing applications at high machining speeds. The built-in pulse picker allows convenient control of the laser output in pulse-on-demand mode. PHAROS compact and robust optomechanical design features stable laser operation across varying environments.
