Narrow line single frequency (longitudinal mode) SLM lasers, Oxxius

Home PRODUCTSLaser and light sourcesSingle frequency lasers (SLM)

Narrow band or emission lasers, also called single-frequency lasers or Single Longitudinal Mode lasers (SLM), are indicated for applications where spectral line narrowness or coherence length are fundamental parameters. SLM lasers (single frequency lasers) have much smaller bandwidths (typically 50 - 300 MHz, that is, 0.1 - 0.5 pm) and may have coherence lengths of up to 100 m.

The best known applications of narrow emission lasers (single frequency lasers or single longitudinal mode lasers) are: bioscience (biomedicine, fluorescence, excitation, absorption), confocal microscopy, holography, replacement of He-Ne lasers, LIDAR, metrology, Raman spectroscopy, Speckle interferometry, Photodynamic therapy, interference lithography, etc.

Iberoptics can offer different single frequency laser families (SLM lasers) depending on your needs. These families are summarized on the following table:

Family	Lambda Beam Wavelock	Measurement&Spectroscopy (OXXIUS)
λ (nm)	405, 633, 640, 660, 685, 690, 785, 808, 830	532.3, 553, 561.4, 632.5, 785, 830, 1064.3
Mode	TEM00*, SLM	TEM00, SLM
Spectral linewidth	<0.1 pm - 0.15 nm	< 1MHz (532, 553, 561,1064 nm), <100 MHz (633, 785, 830 nm)
Coherence length	4.5 mm - 2 m
Power (mW)	10 - 500	up to 500 mW
Notes	High λ stability (<0.015 nm), excellent beam quality, low noise	Exceptional wavelength stability (<1 pm)

* 830 nm laser emission is transversal multimode
