Frequency quadrupled Fiber Ultraviolet Laser
Precilasers offers high power, single-frequency tunable UV lasers from 250 to 400 nm, for applications in quantum sciences such as cold atoms, ultra-cold molecules,
single-photon excitation of Rydberg atom and frequency standard.
UV laser is obtained by combining an all-fiber amplifier seeded with an ultra-narrow linewidth laser,
a single-pass frequency-doubling unit with PPLN crystal and a cascaded enhancement resonant cavity.
These lasers has the characteristics of narrow linewidth, linear polarization and tunable. After active power control, the output power RMS of the laser is less than 1.0% within 3 hours.

Features:
- Simple structure single pass frequency doubling
- High efficiency external cavity resonance frequency doubling
- High output power
- low intensity noise
- narrow linewidth
Applications:
- Single photon Rydberg excitation of Rubidium atom (297 nm)
- Beryllium ion cooling (313 nm)
- Grating writing (390 nm)
- Calcium ion optical clock (397 nm)
- Ytterbium atom cooling (399 nm)
Specification
The 1050nm and 1550nm lasers with narrow linewidth are used as seed sources respectively.
After amplification by single frequency fiber, the two lasers generate 626 nm laser with narrow linewidth
and high power utilizing the periodically polarized crystal SFG. By cascading an efficient external resonant cavity,
the wavelength of the laser is converted to ultraviolet band at 313 nm.
Compared with cascading two resonant cavities with diode laser and tapered amplifier,
our product has more compact and stable structure, larger output power of laser.
