We have observed intervalence band laser action in Al-doped germanium crystals with volumes as small as 0.03 cm{sup 3}, one order of magnitude smaller than previously studied {ital p}-Ge laser crystals. A duty cycle of 1.5{times}10{sup {minus}4} was achieved. We show evidence that crystal heating plays a key role in the duration of the emission pulse and have measured a maximum pulse length of 11 {mu}s for a 0.43 cm{sup 3}, Ga-doped germanium crystal. Such progress in the understanding and performance of {ital p}-Ge hot hole lasers marks a significant step toward continuous wave operation.
