Abstract
A laser comprising: a front mirror and a rear mirror which are disposed so as to establish a reflective cavity therebetween; a gain region disposed between the front mirror and the rear mirror, the gain region being constructed so that when the gain region is appropriately stimulated by light from a pump laser, the gain region will emit light; and one of the front mirror and the rear mirror being positioned to admit pump light into the reflective cavity, the one of the front mirror and the rear mirror having a low and substantially constant reflectance over a pumping wavelength range and having a high and substantially constant reflectance over a lasing wavelength range.
