Single Frequency Lasers

Power, Coherence, Stability

TOPTICA's single-frequency diode lasers employ state-of-the-art diode technology to achieve the highest single-frequency output power of any direct diode-based system. For example, the TopMode 405 nm model offers as much as 100 mW – an industry record!

At the well-established HeNe wavelength of 633 nm, the corresponding system provides an output of 50 mW. Even Watt-class UV/RGB solutions are provided by frequency-converted diode lasers. TOPTICA's single-frequency lasers feature a narrow spectral width, translating into a long coherence length. All models exhibit an excellent stability of wavelength and output power, combined with TEM00 operation mode.
