New Fiber-Pigtailed Visible Sapphire Lasers from Coherent

Coherent of Santa Clara, California, has added a new assortment of fiber-pigtailed (FP) lasers to its collection of FP products. The lasers can be obtained at seven different wavelengths, such as 458, 488, 514, 532, 552, 561 and 588 nm, at output strength of up to 120 mW.

They are basically designed with1 m of polarization-sustaining, single-mode fiber, culminating in a customary FC/APC 8„a connector, thus being easy to use, be it in integration into OEM implements or in stand-alone applications.

Sapphire FP lasers are CW, concise visible lasers that proffer a distinct mix of low noise (<0.25% RMS at 10 Hz to 2 MHz), superior output stability (<„b2% over 2 hours „b 3„aC after warm-up), and a wide ambient temperature functioning range (10„aCƒ{40„aC) because of several reasons.

The first reason is the use of the field-validated (more than 25,000 units) Sapphire laser platform that yields a round output beam with the lowest beam drift in the industry, which enables proficient coupling. The second reason is the use of a permanent rugged fiber pigtailing with the use of PermAlign technology instead of an air-launched arrangement utilizing multi-axis adjustable mounts that almost always drift with the passage of time. The high-quality stability-promoting design will allow the fiber to be a vital part of the resonator plate presenting PermAlign technology, physically totally unconstrained by the external housing. Besides, a unique fiber termination enables operating the Sapphire FP lasers at short wavelengths and/or high power without fiber deterioration or damage.

The usual usages of Sapphire FP lasers are in fluorescence-based techniques where fiber delivery is generally used to enable miniaturization, such as confocal microscopy or flow cytometry.
