TopMode
Powerful and Coherent Diode Lasers
Diode laser with best wavelength / coherence stability
Wavelengths: 405 and 633 nm
100 mW single-frequency power @ 405 nm
Includes active coherence stabilization (CHARM)
For metrology, interferometry, Raman spectroscopy
TOPTICA’s TopMode lasers operate as easily as a HeNe, but also offer higher power and blue wavelengths. The TopMode series sets records in terms of power, coherence and wavelength stability. The proprietary CoHerence-Advanced Regulation Method (CHARM) provides an active stabilization of the lasers’ coherence and ensures continuous single-frequency operation. TopMode and CHARM means nothing less than reliable 24/7 operation.
