DopplerLite and DopplerPower DPSS Lasers
DPSS (Diode Pumped Solid State) lasers have recently become available with power levels suitable for LDA and PDA. The great advantages of DPSS lasers over Argon-Ion lasers are the compact size, much lower power and cooling requirements and hence lower operating cost. Two of the three proposed DPSS lasers can replace Ar-Ion lasers without need to change any optical components, because the wavelengths are nearly the same.
The DopplerLite is available in two versions. The 2 x 100 mW version uses 491 and 515 nm lasers and can directly replace an air-cooled Ar-Ion laser. The 2 x 150 mW versions uses different wavelengths and is offered with a modification package for FiberFlow transmitter and receiver optics. Both are silent because there are no cooling fans. The DopplerPower provides 2 x 1 W in 488 and 514 nm and can directly replace a water-cooled Ar-Ion laser.Kembali
