…resulted in laser diodes with output
throughout the visible spectrum. This has led
companies such as Coherent to develop highperformance packaged modules with long lifetimes
based on these visible laser diodes.
The Coherent OBIS family (see Figure 1) uses laser
surge and reverse polarity protection.The nominal
operating temperature range is -10 to +40°C. Diode
lifetime will be greater at lower temperatures.
…your Coherent structured laser light generator has been
developed with the end-user in mind. The Magnum II laser features
high quality glass optics and a rugged housing to maximize the
laser's reliability. To ensure longer lifetime, all diode lasers have
undergone a burn-in…
