Coherent’s Sapphire 488 LP bioinstrumentation laser offers 150 mW of CW output at 488 nm, while the Sapphire 561 LP provides 200 mW of power at 561 nm. These new lasers, available in an OEM and CDRH configuration, measure 125 x 70 x 34 mm, making them easy to integrate into benchtop instrumentation. Offering high efficiency, the optically pumped semiconductor laser (OPSL) technology produces minimal waste heat. A USB port interface (OEM version only) enables simple software control of laser operation and readout of all laser operating and status parameters. Also, a new OEM controller board is approximately half the size of the prior version. Both lasers are suited for life science applications, such as flow cytometry, confocal microscopy, and sequencing in genomics and proteomics. In these uses, their small size and high output power enable the construction of compact instrumentation. They deliver high beam quality (M2<1.1), low noise (<0.25% rms from 20 Hz to 2 MHz) and high pointing stability (<30 µrad), resulting in stable, low-noise instrument operation.
