Where to Buy Single-frequency Lasers

All of TOPTICA’s tunable diode lasers offer a narrow linewidth of typically 100 kHz, corresponding to coherence lengths of almost 1 km. By stabilizing these lasers even further with TOPTICA’s locking electronics, linewidths below 1 Hz are possible.

ALPHALAS offers CW or pulsed single-frequency lasers (single longitudinal mode) with TEM₀₀ beam profile at most of the standard laser wavelengths. Various proprietary and standard technologies including monolithic non-planar ring oscillators (NPRO), DFB and unidirectional ring laser designs are used to achieve stable single-frequency operation with a very low intensity noise. The output power in CW mode ranges from several tens of mW to > 10 W at 1030 nm and 1064 nm. The single-frequency Q-switched lasers offer the unique combination of very narrow spectrum (transform-limited pulses) with very low amplitude noise due to the absence of mode beating.

Applications include high-resolution spectroscopy, interferometry, holography, optical metrology, meteorology, efficient Brillouin- and Raman-shifted generation, Raman spectroscopy and optical trapping, to mention just a few of them.

Menlo Systems offers ultrastable frequency-stabilized lasers at basically any wavelength. We supply fully characterized systems with linewidths <1 Hz and Allan deviations of 2 × 10⁻¹⁵ (in 1 s) as well as modules and components allowing for state-of-the-art systems tailored to your requirements.

The Koheras narrow linewidth, single-frequency fiber lasers are ultra-low noise sources with longitudinal single-mode and single-frequency operation. The lasers are based on a DFB design ensuring robust and reliable operation and are delivered as fully integrated systems for industrial and scientific applications. Koheras offers an unprecedented low phase- and intensity noise level at Yb, Er, and Tm wavelengths. It has very high stability and mode-hop-free inherent single-frequency output – even when exposed to changing environmental conditions. You can also get shot noise-limited solutions for applications demanding an extra low-intensity noise level.
