Wavelengths of the blue lasers: 473, 375, 405, 390-415, 420, 430, 440, 442, 456, 462, 473 and 488 nm, 430 and 490 nm

The blue laser is easy to use, plug and play, no cooling fan, no cooling water required, no noise and no vibration during laser operation.

The compact blue lasers are based on our proprietary laser design technology. This new technology allows our blue crystal lasers to operate in TEMoo mode with low amplitude noise and extremely low power consumption in a compact laser housing.

For 405 nm, 473 nm and 488 nm Raman or fluorescence excitation, see the Raman laser selection guide and DPSS laser selection guide.

Blue Laser Wavelengths and Applications

Blue lasers cover roughly 440 to 490 nm, and violet lasers 375 to 430 nm. Diode lasers cover 375 to 465 nm with fast modulation. The 473 nm laser is a diode-pumped solid-state (DPSS) laser, made by frequency-doubling Nd:YAG. 488 nm is available in low-noise and single-frequency versions.

Wavelength	Max. TEMoo output	Typical applications
375 nm	60 mW; single-frequency up to 25 mW	UV-excited fluorescence; holography and interferometry with the single-frequency version
405 nm	400 mW; single-frequency 75 mW	Fluorescence excitation (DAPI, Hoechst), Raman, holography with >50 m coherence length
430-465 nm	100-450 mW	Fluorescence, instrumentation, OEM modules
473 nm	260 mW	Channelrhodopsin (ChR2) optogenetics, fluorescence, Raman. CrystaLaser 473 nm lasers in early optogenetics research
488 nm	260 mW	Flow cytometry, GFP and FITC excitation, confocal microscopy

For selection by output type, see the DPSS laser selection guide. For fiber output, see fiber-coupled lasers.
