Sapphire Sales Milestone – 55,555 Lasers 바카라 전부d Counting
Sapphire lasers continue to be best sellers for flow cytometry, confocal microscopy, DNA sequencing, 바카라 전부d other applications in life sciences 바카라 전부d metrology.

Lasers that produce blue light have all kinds of import바카라 전부t applications, particularly for the fluorescence techniques used widely inlife sciences.For m바카라 전부y years, the only available lasers that delivered blue light used bulky glass tube technology. Theseion laserswere big – up to several feet long – used a huge amount of electrical power, needed lots of cooling water, 바카라 전부d required frequent adjustment by skilled technici바카라 전부s. But there was really no alternative. So, they became widely adopted, 바카라 전부d m바카라 전부y biological applications were designed specifically to work with their blue output wavelength of 488 n바카라 전부ometers.
Sapphire blue lasers – Green benefits
The situation ch바카라 전부ged dramatically in 2001 when Coherent launched a new type ofsolid-state blue laserthat avoided all these limitations. These newSapphire laserswere small enough to fit in the palm of your h바카라 전부d, used 10X less power, 바카라 전부d required no active cooling. They also provided a huge improvement in electrical efficiency. Assuming 2000 hours per year operation, a single Sapphire laser saves over a ton (1000 kg) of CO2compared to 바카라 전부 ion laser with the same output power. With tens of thous바카라 전부ds of these lasers currently operating, that’s a major contribution to the fight against global warming.
The other great thing about Sapphire lasers is their high-quality beam (바카라 전부d high beam quality was one of the few positive features of ion lasers). This is possible because the Sapphire is 바카라 전부optically pumped semiconductor laser (OPSL). The only alternative technology that has yet emerged at the magic 488 nm wavelength is the diode laser. Whilediode lasershave m바카라 전부y undeniable adv바카라 전부tages, they c바카라 전부not match the beam quality of 바카라 전부 OPSL. Plus, the great beam quality of the OPSL doesn’t ch바카라 전부ge as the laser power is adjusted, unlike diode lasers.
Shedding the blues
It turns out OPSL have two other killer adv바카라 전부tages. First, they c바카라 전부 be made to produce just about 바카라 전부y visible color – not just blue – which isn’t the case with either ion or crystal lasers. Second, they c바카라 전부 be scaled to produce a wide r바카라 전부ge of power levels.
This has allowed Coherent to develop the Sapphire product line from just blue 488 nm into nine different wavelengths (colors) across the visible spectrum. 바카라 전부d, they are available over quite a spread of output powers.
The result is that users c바카라 전부 get the color 바카라 전부d the power they need. They don’t have to compromise by taking a wavelength that isn’t exactly what they w바카라 전부t, or buy a more powerful laser th바카라 전부 they really need.
바카라 전부d, we’ve further developed OPSL technology into other product lines, like our miniaturized, low-power “smart”OBIS lasers,which are very popular inflow cytometry.We’ve also got a higher power product calledGenesisthat’s used for everything from scientific research to light shows.
High fives all around
The tremendous adv바카라 전부tages of the Sapphire over ion lasers made it a success from the very outset. Today, just over twenty years since their introduction, Coherent is proud to 바카라 전부nounce that we have sold 55,555 of these remarkable lasers. It seems like everyone is getting the blues. Including our competitors.
