Buying Single-frequency Lasers

Top-level product category: lasers and laser amplifiers

More general product categories: narrow-linewidth lasers

More specific product categories: narrow-linewidth lasers, nonplanar ring oscillators

Related product categories: optical frequency standards, photon Doppler velocimetry equipment

Single-frequency lasers produce light with a very narrow linewidth, suitable for applications requiring high frequency stability and no mode hops. They are used in interferometry, laser spectroscopy, and optical communications. High-power single-frequency lasers are also employed in coherent beam combining techniques.

single-frequency lasers

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.
