The R0638 is a set of 638nm wavelength stabilized diode lasers with a wide range of configuration options. Our proprietary wavelength stabilized lasers feature stable (≈ 1% power stability), high output powers with ultra-narrow spectral bandwidths, and a diffraction-limited output beam. Designed to replace expensive DFB, DBR, fiber, and external cavity lasers, our multi-mode spectrum stabilized lasers offer superior wavelength stability over time, temperature (0.007 nm/0C), and vibration, and are manufactured to meet the most demanding wavelength requirements.
The TO-56 & 14-Pin Butterfly packaged, base product lines come standard with a circularized and collimated open output beam, internal thermistor, and ESD protection, while the 14-Pin Butterfly package can also be fiber-coupled (expect ≈ 50% power loss from base values with fiber-coupling). Utilizing a hybrid external-cavity laser design, based on volume Bragg grating (VGB) technology, we ensure extremely narrowband (≈ 100kHz) output, with a precisely defined center wavelength and a very low sensitivity to temperature changes. Lasing wavelength can be accurately specified and repeatedly manufactured to within +/-0.1 nm upon request. The R0638 also provides an excellent side mode suppression ratio (SMSR), which is typically between 35-45 dB.
