SINGLE LONGITUDINAL MODE / SINGLE FREQUENCY LASERS

Lasermate Group, Inc. offers a wide selection of single frequency/single longitudinal mode (SLM) lasers with features of narrow linewidth <0.00001nm, long conherent length >100m, frequency stabilized and >1MHz modulation. The laser operates in single longitudinal mode and TEM00 mode with low amplitude noise and high stability. The single longitudinal mode lasers are widely used in applications of Raman spectroscopy, holography, biomedical/fluorescence, interference lithography, precision measurement, atomic excitation/absorption, and semiconductor inspection.


Single Longitudinal Mode Lasers

Lasermate Group, Inc. supplies compact diode pumped solid-state DPSS single frequency/single longitudinal mode lasers with <0.00001nm narrow linewidth and long coherent length (e.g. >50m for 532nm) at wavelengths of 360nm, 457nm, 473nm, 523.5nm, 526.5nm, 532nm, 556nm, 561nm, 577nm, 589nm, 639nm, 656.5nm, 660nm, 671nm, 721nm, 1047nm, 1053nm, 1064nm, 1313nm, 1319nm and 1342nm. These lasers operate in the single longitudinal mode and TEM00 mode with low amplitude noise and high stability.

Frequency Stabilized Single Longitudinal Mode Lasers

In addition to features of narrow linewidth and long coherence, Lasermate Group, Inc. offers frequency stabilized single longitudinal mode lasers that have the advantages of stable frequency and low frequency noise. They are used in optical frequency standards, gravitational wave detection, tests of fundamental physics, atomic clocks, high resolution spectrum, laser radar, precision measurement and many other applications.

  • Frequency shift (8 hours): +/- 200MHz

  • Frequency shift with Temperature: <200MHz/oC

Frequency stabilized single frequency lasers are available at wavelengths of 360nm, 457nm, 473nm, 532nm, 556nm, 561nm, 639nm, 656.5nm, 660nm, 671nm, 721nm, 1047nm, 1053nm, 1064nm, 1313nm, 1319nm and 1342nm.

>1MHz Modulated Single Longitudinal Mode Lasers

Furthermore, Lasermate Group, Inc. provides high frequency modulated single frequency lasers that exhibit the advantages of quick modulation rate, high extinction ratio and easy coding.

  • Repetition rate: Up to 1MHz

Our >1MHz modulated single longitudinal mode lasers are available at wavelengths of 473nm, 532nm, 556nm, 561nm and 671nm.
