Abstract
- A tunable laser optical source equipped with wavelength and mode-hop monitors was developed to compensate for thermal expansion of the medium in holographic data storage. The laser's tunable range is 402-409 nm, and supplying 90 mA of laser diode current provides an output power greater than 40 mW. The aberration of output light is less than 0.05 [lambda]rms. The temperature range within which the laser can compensate for thermal expansion of the medium is estimated based on the tunable range, which is [+ or -]13.5 [degrees]C for glass substrates and [+ or -]17.5 [degrees]C for amorphous polyolefin substrates. OCIS codes: 090.7330, 140.3600, 210.2860.
