Coherent has introduced a solid-state optically pumped semiconductor laser (OPSL) with output at 552Nm, suitable for applications including flow cytometry, confocal microscopy and drug discovery.
These new Sapphire 552 LP lasers offer continuous wave (CW) output of 50mW, 75mW, 100mW, 150mW and 200mW.
They also provide a diffraction-limited beam (TEM00, M<1.1) with pointing stability of < 5urad/C, power stability of < two per cent and noise of < 0.25 per cent rms from 20Hz to 2MHz.
Sapphire 552 LP lasers come with a compact laser head, measuring 125 x 70 x 34mm.
This is identical to all other Sapphire LP lasers, independent of wavelength and power class, to simplify integration including wavelength addition and substitution for OEMs and end users alike.
As with other Sapphire LP lasers, the new 552Nm models are equipped with USB, RS-232 and analogue interface ports for ease of installation and operation.
Sapphire lasers are based on Coherent's optically pumped semiconductor laser (OPSL) technology.
One of the main benefits of OPSLs is wavelength scaling: the possibility to build OPSLs at nearly any visible wavelength.
This has created a paradigm shift in visible laser applications where laser output is matched to key applications instead of vice versa.
Unlike many other solid-state lasers, OPSLs do not suffer from thermal lensing, so the output power of any Sapphire LP can be smoothly adjusted from 10 to 110 per cent of nominal power with no effect on beam quality.
Sapphire 552 LP lasers are intended for life sciences applications including flow cytometry, confocal microscopy and drug discovery.
Because this wavelength is well-separated from popular laser wavelengths such as 532Nm and 568Nm, it is suitable for instrument builders and end users looking to increase the number of fluorophores they can simultaneously detect without crosstalk.
